Route blame between Processor and Coordinator (#427) 
* Have processor report errors during the DKG to the coordinator

* Add RemoveParticipant, InvalidDkgShare to coordinator

* Route DKG blame around coordinator

* Allow public construction of AdditionalBlameMachine

Necessary for upcoming work on handling DKG blame in the processor and
coordinator.

Additionally fixes a publicly reachable panic when commitments parsed with one
ThresholdParams are used in a machine using another set of ThresholdParams.

Renames InvalidProofOfKnowledge to InvalidCommitments.

* Remove unused error from dleq

* Implement support for VerifyBlame in the processor

* Have coordinator send the processor share message relevant to Blame

* Remove desync between processors reporting InvalidShare and ones reporting GeneratedKeyPair

* Route blame on sign between processor and coordinator

Doesn't yet act on it in coordinator.

* Move txn usage as needed for stable Rust to build

* Correct InvalidDkgShare serialization

Distributed Key Generation

A collection of implementations of various distributed key generation protocols.

All included protocols resolve into the provided Threshold types, intended to enable their modularity. Additional utilities around these types, such as promotion from one generator to another, are also provided.

Currently, the only included protocol is the two-round protocol from the FROST paper.

This library was audited by Cypher Stack in March 2023, culminating in commit 669d2dbffc1dafb82a09d9419ea182667115df06. Any subsequent changes have not undergone auditing.
