Pull request description:

  ### Description

  Update BDK to the latest version, 0.24.0.

  ### Notes to the reviewers

  I also had to add `base64` as a new dependency because it's not exported by `bdk`.

  There's probably a more elegant way to fix the `wasm.rs` compiler function for descriptor.translate_pk, and I don't
  know how create a unit test it since it only runs on wasm32. But at least it builds so I think that's close enough for now.
