GitHub Action to add to a workflow, to keep in check those windows developers who have given up understanding git's autocrlf setting and/or forget to handle line endings on their side.

Uses grep on a docker container.

By default checks all files in the repository (excluding the .git folder), but can be given a list of separate directories to check.

Most of the work was done by @Rotendahl, I mainly copy-pasted stuff from stack overflow :)
