- refactor the caching logic given the GitHub action limit on arguments is too small to allow passing in the whole cache

- adjust the `cache` to now only take the file-path to read the cache from
  - offer temporary backwards compatiblity on passing the cache directly
  - add documentation for cache vars in README
