Generate the group commitment from all round one signing commitments as part
of aggregate(). Only re-derive a commitment share from the signing share
as part of signing share verification, just before aggregate.
* WIP
* Using H1/H2/H3 per spec, the verification still fails with Verificationkey
* Use FROST spec hashes, update all challenge generations to be DRY
Make clippy happy, etc
* DRY up generate_challenge
Also rename all methods to be generate_ instead of gen_
* start messages and validation
* add missing docs to constants
* change validation to matches, fix constant doc

* fix the build
* validate share_commitment
* add new constants and validations
* fix validation
* derive serde Serialize and Deserialize in all messages structs
* update created structs

* fix build
* define and use a new MAX_SIGNERS constant
* change group_public type
* add some test cases
* add validation and serialization tests for SigningCommitments
* add validation and serialization test to SigningPackage
* change some fields order matching the spec
* fix field order in tests according to last updates to the spec
* implement serialize and deserialize for ParticipantId
* move serde-json to dev-dependencies section
* change to pub(crate)
* fix serialize of VerificationKey
* add assert to serialize
* add note, fix typo
* improve some code in tests
* test serialization of individual fields
* start messages and validation
* add missing docs to constants
* change validation to matches, fix constant doc
