We would like the PSBTv0 code to be as close as possible to the code we originally imported from rust-bitcoin and rust-miniscript. This gives us a few things:
Same code means downstream can easily switch from using the psbt modules in rust-bitcoin and rust-miniscritp, hopefully just need to change import paths.
Re-basing on new versions of the original code will be easier and less bug-prone if the files stay as close to the same as possible.
Re-import the original code, make as few a changes as possible to get it to build. Use the same directory structure as the original, unlike what we did when we originally imported the code.
Note, this patch is not PSBTv2 compliant because deserialization of v0 PSBTs does not fail for excluded map keys. That will be added in a subsequent patch.
