Specification for UR type 'crypto-psbt'

[craigraw]

Hi,

As discussed just opened a PR for representing PSBTs in UR format: BlockchainCommons/Research#37

As the PR notes, I didn't feel there would be value in trying to copy data out of the PSBT into CBOR, and PSBTs are meant to be self-contained anyway. So I have used a simple CBOR byte string for maximal efficiency, given PSBT is a binary format. The value of the specification lies in knowing that you are dealing with a PSBT from the UR type.

Thanks Craig, I certainly agree with this approach and look forward to adding it into my projects.

Thanks @Fonta1n3 - Chris is asking for another ACK on the PR before merging if you are happy to proceed.
