§Distributed Key Generation - PedPoP

This implements the PedPoP distributed key generation protocol for the dkg crate’s types.

This crate was originally part of the dkg crate, which was audited by Cypher Stack in March 2023, culminating in commit 669d2dbffc1dafb82a09d9419ea182667115df06. Any subsequent changes have not undergone auditing.
