[cr_checker]: Allow for directories & comments in ignore file

[MaximilianSoerenPollak]

Feature Request / Modification Description

The ignore file that can be passed to cr_checker does currently not support directories or comments (to make the file easier organizable).

This should be supported.

Instead of writing:

ignored_dir/file1.txt
ignored_dir/file2.txt 
...

I want to be able to write:
ignored_dir/*

And ignore all files & dirs inside for example.
