Build: Setup initial hardhat compilations

[CruzMolina]

• build: add hardhat as devDep
• build: initial hardhat config w/ solidity settings
• refactor: add artifacts & cache to gitignore
• build: add npm hardhat compile script
• refactor: port hardhat config from js to ts
• refactor: rm unused calculateContractBytecode script
• build: add calculate-contract-bytecode npm script

Why removing calculateContractBytecode script ? I sometime use it to check contract bytecode size, I think it is useful.

This is good, I think it will be great if u do a walkthrough of the setup or hardhat overall in a learning session before merging this.

Ah, my bad @haythem96 . It looked like an unused script. Will re-add.

Use this instead of the script: https://hardhat.org/plugins/hardhat-contract-sizer.html

[CruzMolina]

@antoncoding the output of the script that plugin runs is different than the calculateContractBytecode script. hardhat-contract-sizer outputs a table of each contract's bytecode size in KB but doesn't show how much space is left.

What do you think @haythem96?

Also, IIRC, by default ganache-cli maintains the EIP-170 limit. A contract breaching the limit should not deploy locally.

Yes that's true, I think it is fine to keep the script, it is already working and doesn't need any maintenance even if we don't mainly use it, so I don't see a cons of keeping it.

@haythem96 the issue I see with keeping is that it's very specific to truffle's framework. However, if we decide to remove truffle as a devDependency, it shouldn't be difficult to modify the hardhat plugin script to also calculate and provide similar output.

I think we can keep it for now, and open another PR to modify all truffle script to hardhat, and then remove truffle as dev dependency
