Generate valid ABI and Typechain for anticipated Diamond Cut

[cha0sg0d]

The problems we have identified:

1. If we have two functions with the same signature (example: initializePlayer in DFCore and initializePlayer in DFArena), we can't build the Diamond ABI due to the overlapping function check (strict = true).

2. If we have two functions with the same name but different types, we have a problem with ethers where need to fetch the functions with await sampleContractEthers["overloading()"](); , which breaks most existing calls and tests that expect the standard sampleContractEthers.overloading() getter.

See #3 for proposed temporary solution.
