Runs https://github.com/AntonStoeckl/go-mutesting as Github Action. Used a fork of the original go-mutesting tool since the forked version can be used with Go modules.

See the repository's README for details about the usage of go-mutesting.

Contributions are very welcome! If you find anything that can be done better, anything that's missing or have general questions/issues feel free to open an issue or file in a pull request.
