hardhat-tracer v2

Improvements

• Performance improvements by directly using hardhat vm. Consumes minimal RAM as compared to v1 implementation.
• tracecall task allows to perform arbitary calls on mainnet to inspect state.
• State overrides allows to set storage, bytecode, balance, nonce for any address, which can be useful to see how a mainnet tx trace would be with local solidity contracts code (containing any console logs for mainnet debugging).
• Faster abi decoding by using 4byte directory.
• Allows to print trace for just failed txs or calls while running tests using --v or --vv, or everything using --vvv or --vvvv.
• Adds chai assertion method for expecting internal message calls, e.g. expect(hre.tracer.lastTrace()).to.have.messageCall(await contract.populateTransaction.someMethodInCalledInTx(param1, param2))
• Export trace in JSON formats.
