Setup GitHub (#2)

* Fix license identifier
* Add CI tests

A cached setup that includes cargo check, clippy, fmt, and test

* Fix formatting
* Remove explicit rustup install

cargo, etc. is already installed, see:
<https://github.com/actions/runner-images/blob/main/images/linux/Ubuntu2204-Readme.md>

* Add more context to cache prefix-key
* Apply suggestions from code review
* Ignore non-rust files
* Remove unused matrix testing key
* Use a better filename
