Module opret

Processing proprietary PSBT keys related to OP_RETURN (or opret) commitments.

NB: Wallets supporting opret commitments must do that through the use of deterministic bitcoin commitments crate (bp-dpc) in order to ensure that multiple protocols can put commitment inside the same transaction without collisions between them.

This module provides support for marking PSBT outputs which may host opret commitment and populating PSBT with the data related to opret commitments.
