- Move bulk of verification to curves/Bn254Proofs.sol
- remove all unneeded structs and add Proof struct
- bring in point `isOnCurve` check so that we can use solidity compiler 0.8.x
- remove all other Bn254 library deps
- changed proof type from bool to Proof
- add Bn254 test file (uncalled yet)
TODO:
- update Proofs test such that verifyProof test is called (need to generate proof using https://github.com/status-im/nim-codex/pull/76)
- call Bn254 tests from test harness
