I'll work on TxIn

Next up is Transaction. I will have a look at what API surface we need for bdk-ffi and ldk-node

High level question; based on discussion bitcoindevkit/bdk-ffi#469 do we want to create a new miniscript-ffi crate to put types like PsbtExt(Psbt).finalize() ? or we could include miniscript as a dependency to this crate. I'm leaning to including miniscript here since I don't see any project using something like a miniscript-ffi create and not also needing the bitcoin-ffi types.

[notmandatory]

If we do add miniscript to this crate then we could implement the PsbtExt::finalize() as a function directly on the bitcoin-ffi Psbt type.

[thunderbiscuit]

Yes I recommend we (for now at least) think of bitcoin-ffi as encompassing what we need from the rust-bitcoin org (probably just bitcoin and miniscript but maybe also bitcoin_hashes and core).

Could also be same repo, but different crates?
