WIP: reorg curves, use witnet as base 
Now that curve ops are transactions, need to change up tests so that we can verify the result somehow? https://docs.ethers.io/v5/api/contract/contract/#Contract--write

WIP: Add test for verifier 
Needs valid values to test points that exist on the curve as well as a valid proof. Waiting on https://github.com/status-im/nim-codex/pull/101 to get valid values.

TODO: Convert Bn254.sol contract to a generic witnet EllipticCurve.sol contract and fill in values as needed for the Bn254 curve.

WIP: reorg to allow for more curves 
Current tests are failing because ECMUL is not a valid opcode in hardhat. Exploring alternatives.

chore: clean up 
- 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
