### ToDo:
- [x] ~~`newPublicKey` - accepts also a private key without error~~
- [ ] `signatureFromHex` - unwrap
- [x] ~~`queryMailbox` - unwrap when witness incorrect~~
- [x] `queryMailbox` - witness can start with both B and D, no difference
- [ ] `queryMailbox` - witness starting with D is listening, no error when we pass witness starting with B
- [x] ~~`finalizeMailBoxQuery` - if the signature is incorrect, throws Ffiexception with witness error~~
- [x] ~~`inceptGroup` - witness treshold lower than 0/huge works~~
- [x] ~~`inceptGroup` - signature treshold unwrap~~
- [ ] `inceptGroup` - think about exception when initialWitness is incorrect
- [ ] ~~`inceptGroup` - when participant/identifier is unknown, unwrap~~
- [ ] `finalizeGroupIncept` - works when provided toForward signature from other event, not exn
- [ ] ~~`finalizeGroupIncept` - when provided wrong event, unwrap~~
- [ ] `finalizeGroupIncept` - works when provided signature from other event
