MuSig Aggregatable Schnorr

[drewstone]

Overview

Create a blueprint that does multisignature process. I.e.

1. Service instance specifies a m of n scheme.
2. Operators sign message from event or from some job.
3. They gossip it to other operators using gRPC server or P2P
4. They aggregate using aggregatable scheme or they collect all and submit onchain.
