Slow Execution Time on Large Projects

[ForberichN]

I'm currently trying to implement snitch on a Unity Game engine project the project is pretty early in its development but a simple snitch list takes around 36 Seconds. This probably comes from the large amount of none code files that are still getting analyzed (it even finds TODOs inside of EXE files written in GO).

It would be nice to have the option to have snitch ignore certain files per default like EXE and DLL/SO files which will almost certainly never contain relevant TODOs.

And for more project-specific files it would be nice to be able to define file extensions to ignore in the YAML config.
