Merge bitcoindevkit/bdk-cli#118: Update bdk dependency to 0.22

e8b20287455e7f4fcf87efc8bf74af3f9accbb38 Update bdk dependency to 0.22 (Steve Myers)

Pull request description:

  ### Description

  - 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.**
