Repository: bitcoindevkit/bdk-ffi (language: python)

Issue:
Publish the rust-bitcoin types in their own crate
The types that reside in the current `bitcoin.rs` file are the ones that come from the rust-bitcoin crate. I have made good progress to pull those out of this repo and allow them to live in a separate crate and simply be imported. This has serious advantages in the long run:
- It allows other bitcoin projects that build language bindings using uniffi to leverage these types without re-writing them and maintaining them themselves
- If other projects also use those types, it brings more eyes and review on the codebase
- We potentially pool the burden of development and exposing of more rust-bitcoin types among more projects



Discussion / hints:
I have be quite successful at migrating Kotlin and Python to [this temporary crate](https://github.com/thunderbiscuit/rust-bitcoin-ffi). You can [see the PR here](#546).

My current issue is around how to build the Swift package in a way that types from the bdk library can see and use the types from the rust-bitcoin library.
