- A WasmWallet structure, to create a wallet and run commands
- A compile function, to compile policies into descriptors

`open_database` avoids creating a wallet dir if...
...not necessary
This is useful for the wasm integration, where we want to call the
`open_database` function directly, without wanting it to create any
directories.
Note that when using bdk-cli normally, it won't create a db directory
if it's useless, but it will still create a base directory (even if
empty). This is suboptimal, but fixing it would require a quite big
refactor to the code.
After #99 the previous documentation have been removed and new docs as per `structopts` documentation. This PR adds more documentation across the crate..
This PR is above #102 , to accommodate all the further refactoring changes.
The Readme About section have been updated with more details.. Readme format made aligned with the BDK project itself..
The Readme file is used itself as the crate level documentation in docs.rs too..

On the name :
If Bitcoin wallet devs had to have a "calculator", this is what it might look like. One single interface to do all wallet and node operations.
This PR does the following
- Update electrsd to latest version. We need this to use it for out auto deployed backends.
- Add the remaining codes to `nodes.rs` module to define basic node operation apis on the `Nodes` enum.
- Add a new `node` command in ` CliSubCommand` which has its own subcommand `NodeSubCommand`, These subcommands are essentially `bitcoin-cli` calls. And only the basic ones are included so far. We can also compose multiple `bitcoin-cli` calls to create our own commands in future.
- Update the `handlers` to handle newly added `NodeSubCommands`.
- Update in `utils` :
- This includes handling auto blockchain client creation for `regtest-*` features.
- update on the directory creation workflow. We are creating many directories for many stuffs, and I was trying to figure out the easiest way to keep the whole datadir struct intact, no matter where the user points its `datadir` to. Note that now `datadir` is a global app option, not just available for `regtest` nodes. Default `datadir` is the previous `~/.bdk-bitcoin`.
- Finally add an integration test in `tests/integration.rs` that runs a basic wallet operation with a bdk-cli wallet connected to auto deployed regtest-bitcoin/electrum.
### Notes to the reviewers
@sandipndev @krtk6160. I feel this PR is now ready to try out #87 .
Also looking for more integration test ideas too add into.
basic `node` usage looks like this
```
$ ./target/debug/bdk-cli node --help
bdk-cli-node 0.5.0
Regtest Node mode
USAGE:
bdk-cli node <SUBCOMMAND>
FLAGS:
-h, --help
Prints help information
-V, --version
Prints version information
SUBCOMMANDS:
generate Generate blocks
getbalance Get Wallet balance
getinfo Get info
getnewaddress Get new address from node's test wallet
help Prints this message or the help of the given subcommand(s)
sendtoaddress Send to an external wallet address
```
The biggest benefit is I think in the `repl` mode. That now kinda becomes an integrated tool the like python interpreter to operate a bdk-cli and a bitcoin backend from one single interface.
I am excited to see what kind of demonstrations with bdk-cli we can create with this..

- Update the handlers to handle node commands
- Main `handle_command()` function signature changed to only take
in a `CliOpts`. This is helpful for wasm or any other binding
produced on bdk-cli.
- Update `bdk` and `bdk-reserves` to v0.22.0.
- Change rpc `--skip-blocks` option to `--start-time` which specifies time initial sync will start scanning from.
### Notes to the reviewers
I haven't verified the bits and bytes of the new `reserves` PSBT in the tests. I assume it's different for the same reason as the other tests in `bdk-reserves` when we switched to bdk 0.22, but I could use some help confirming that.
**This is draft until `bdk` and `bdk-reservers` v0.22 are published.**

### Description
This is a massive refactoring PR that changes the whole structure of the crate. Previously it was written like a library
to be used to create the bdk-cli app. But eventually the crate itself became the app. This PR attempts to remove the remaining
lib like patterns in the code, and make it a pure binary crate.
This makes the code more modular and makes it look like a typical binary rust crate.
There was no real good way to structure the change into separate commits, so I made one single big one.. The best way to review is to look at the final structure of the code itself, not the change set.
The crate has following modules now
- `main` : The main app runtime
- `commands`: Includes all the structopt commands used by bdk-cli.
- `handlers`: Include all the command handlers used buy the app.
- `utils`: Include all the utility and helper functions
- `Backend` : Defines the backend node process, and its related methods. (This will be filled more with #92).
Apart from the structure changes there are few other changes that took place
- Almost all of the previous doc comments are removed. As they were written to use bdk-cli as a lib. Instead new structopts "comments" are added to describe the app functionality better. As a result the app `--help` commands are more elaborate and descriptive now. I have also removed few redundant description messages used before, that would mess up the help comments. And as a by product it solves https://github.com/bitcoindevkit/bdk-cli/issues/93.
- bdk is updated to v0.19.0
- bdk-reserves is updated with current version pointing to bdk v0.19.0.
- Default database is now sqlite.
Overall I think I managed not to break anything.
Currently this change will remove most of the previous documentation on the crate. But those aren't useful to context of bdk-cli after this change.. My proposal would be reproduce the README instructions itself in doc.rs landing page.
We also need to update the README to reflect these changes.. I will open that up in a separate PR.
I also haven't updated changelog yet.. Not sure yet how to describe the change in short.. Will do that once this is almost finalized..

### Description
Currently the way `ExternalReserves` functionality is written, it can only be used with `electrum` feature. The tests should fail if the implementation behavior is enforced.. Disabling the tests in CI.
Also removing the `regtest-esplora` features from the tests, because they won't work when #92 lands.

I noticed that when I disable default features and don't enable the `repl` feature that the regex tests fail because they need the regex dependency that the `repl` feature brings in. This PR is to simply disable the regex related test code if the `repl` feature isn't enabled.

### Description
Fixes https://github.com/bitcoindevkit/bdk-cli/issues/55. I decided to go for one feature flag for each backends as they made dependency management easier. Because different backend will have different dependency, and we don't wanna have redundant ones. Also it makes the commands a little shorter.
### Notes to the reviewers
Right now its not that useful because the backend APIs are not exposed. So I can't really do much other than sync/send in the command line. (unlike testnet we cannot send coins to bdk from outside of local regtest node). So to make it useful in repl mode as described in the issue, we also have to expose the blockchain apis in bdk-cli command in some way (at least the basic stuffs, address, send, generate). Looking for suggestions on this.
usage looks like this:
```
cargo run --features regtest-rpc -- wallet --descriptor "wpkh(tpubEBr4i6yk5nf5DAaJpsi9N2pPYBeJ7fZ5Z9rmN4977iYLCGco1VyjB9tvvuvYtfZzjD5A8igzgw3HeWeeKFmanHYqksqZXYXGsw5zjnj7KM9/*)" sync
{}
```
Although I am having trouble connecting to the esplora end of electrs. Not sure whats the issue, will have to look more.

Add auto backend deployment
This adds bitcoind and electrsd deployment and management for each kind
of feature flags. The wallet then gets connected to the backend. All the
backend related args for bdk-cli can be omitted in regtest-* mode.
Also added `verify` feature flag which enables transaction verification against consensus rules during sync.
I also had to disable the `reserves` tests and that feature will be broken until we can get it updated to use `bdk` `0.17` also. I created an issue https://github.com/weareseba/bdk-reserves/issues/4.

This PR adds an optional `cookie` arg to pass on cookie file if user needs to use that instead of basic user:password based authentication.
bitcoin core will only generate a `.cookie` file if rpc username passwords are not set in `bitcoin.conf`. Thus cookie file doesn't have a default. User should only provide it if they know a cookie file exists, or else "File not found" error is returned.

There was an inconsistency in `rpc` tests. The `RpcOpts` was missing from the wallet struct. This wasn't caught before because we didn't have `rpc` tests in CI. Fixed that too.
