Solves issue #1
When the file selection dialog closes without any selection it no longer causes "is no file" and "not a valid mod file" prompts to occur.

Also added dialogs when no game path is set and the selection is cancelled (also fixed a loop with that)
Created a small PyQt6-based window to manage Lethal Company mods by storing their zip files and extracting them correctly into the BepInEx folder and remove them again.
Creates a small config file which is currently set nearby the main.py as a yaml
