 Feel free to open PRs or issues. There is an integration test and one of the mock test cases is expected to fail. If you're adding an option, you can vaildate it in CI by adding it to the mock options config located [here](https://github.com/cgewecke/eth-gas-reporter/blob/master/mock/config-template.js#L13-L19).
