+PSBTv2s can be uniquely identified by constructing an unsigned transaction given the information provided in the PSBT, and computing the transaction ID of that transaction.
 Since PSBT_IN_SEQUENCE can be changed by Updaters and Combiners, the sequence number in this unsigned transaction must be set to 0 (not final, nor the sequence in PSBT_IN_SEQUENCE).
 The lock time in this unsigned transaction must be computed as described previously.
