Support hardhat projects with mythx analyze

[xanderdunn]

• MythX CLI version: 0.6.22
• Python version: 3.8
• Operating System: macOS 12.0.1

Many developers are moving from truffle to hardhat for solidity development. The mythx-cli supports interpreting truffle projects for the analyze function, but I haven't been able to get this to work in a hardhat project.

From the root directory of my hardhat project:

$ mythx analyze
Error: No argument given and unable to detect Truffle project or Solidity files

$ mythx analyze contracts/
mythx analyze contracts/
Usage: mythx analyze [OPTIONS] [TARGET]...

This is the standard issue where solc (0.7.6 in this case) is not finding the dependencies. I'm not sure how to pass the necessary flags to mythx's solc invocation to get compilation to work here. If mythx could pull this from a hardhat project that would be extremely convenient.

This works with mythx-cli on my hardhat project:

mythx analyze --remap-import "@openzeppelin/=$(pwd)/node_modules/@openzeppelin/" contracts/ContractA.sol contracts/ContractB.sol ...
