  <!-- You can erase any parts of this template not applicable to your Pull Request. -->

  ### Description
  We currently only support `sqlite` persistence. This PR adds an alternative `redb` persistence by leveraging Summer Of Bitcoin work on [`bdk_redb`](https://github.com/110CodingP/bdk_redb).
  <!-- Describe the purpose of this PR, what's being adding and/or fixed -->

  ### Notes to the reviewers
  The CI does not pass since `bdk_redb` has a MSRV of 1.85.0 which is in turn due to `redb`. Also `bdk_redb` is yet to published as a crate so currently we use the GitHub version of the same.

  The following script tests a simple scenario of creating a wallet with bitcoind-rpc as chain source , sending funds to an address controlled by the wallet and creating a transaction using the wallet:
  ```
  rm -rf ~/.bitcoin/regtest
  rm -rf ~/.bdk-bitcoin

  bitcoin-cli -rpcuser=alice -rpcpassword=password createwallet alice

  export NETWORK=regtest

  export EXT_DESCRIPTOR=$(bitcoin-cli -rpcwallet=alice -rpcuser=alice -rpcpassword=password listdescriptors true | jq -r '.descriptors | .[0] | .desc')

  export INT_DESCRIPTOR=$(bitcoin-cli -rpcwallet=alice -rpcuser=alice -rpcpassword=password listdescriptors true | jq -r '.descriptors | .[1] | .desc')

  export DATABASE_TYPE=redb
  export CLIENT_TYPE=rpc
  export SERVER_URL=127.0.0.1:18443

  addr=$(bdk-cli wallet -w alice -a alice:password new_address | jq -r '.address')

  bitcoin-cli -rpcuser=alice -rpcpassword=password -rpcwallet=alice generatetoaddress 102 $addr

  bdk-cli wallet -w alice -a alice:password full_scan
  bdk-cli wallet -w alice -a alice:password balance

  recipient=$(bitcoin-cli  -rpcwallet=alice getrawchangeaddress)
  psbt=$(bdk-cli wallet -w alice -a alice:password create_tx --to "$recipient:5000" | jq -r '.psbt')

  signed_psbt=$(bdk-cli wallet -w alice -a alice:password sign $psbt | jq -r '.psbt')
  bdk-cli wallet -w alice -a alice:password broadcast --psbt $signed_psbt

  unset $addr

  addr=$(bdk-cli wallet -w alice -a alice:password new_address | jq -r '.address')
  bitcoin-cli -rpcuser=alice -rpcpassword=password -rpcwallet=alice generatetoaddress 1 $addr

  bdk-cli wallet -w alice -a alice:password sync
  bdk-cli wallet -w alice -a alice:password balance
  ```

  the conf is as follows:
  ```
  regtest=1

  [regtest]
  server=1
  rpcuser=alice
  rpcpassword=password
  ```

  ~~Also removed `sqlite` from default features since we now have an alternative.~~
