Create a new PartiallySignedTransaction class that allows creation, updating and signing of transactions in the PSBT BIP0174 format.
[ ] Create classes for the underlying PSBT data structure: PSBTKeyValue, PSBTMap as Writable classes.
[ ] Create abstract PSBT class for overall data structure: PartiallySignedTransaction. Include interface for updating input/output data, signing, merging, finalizing and obtaining the complete transaction.
[ ] Add write method to PartiallySignedTransaction.
[ ] Create PartiallySignedTransactionV1 to represent the BIP0174 PSBT which is technically v0 but often regarded as v1. Include a create named constructor.
[ ] Implement update methods.
[ ] Implement signing.
[ ] Implement merging.
[ ] Implement finalization.
[ ] Implement transaction construction.
[ ] Add a fromReader factory constructor to PartiallySignedTransaction to check for and return the relevant sub-class: only PartiallySignedTransactionV1 to begin with.
