Generalize the _load_steam_workshop_zips() method

[otDan]

This would be a better option than having a hardcoded way of retrieving those zips, so you can provide a CLI argument that basically says to do a deep search inside the already provided mod path folder

[KANAjetzt]

With that, we might have the possibility to move ModLoader._load_mod_zips() to _ModLoaderFile.load_mod_zips() as intended in #255. This is currently not possible due to cyclic dependencies.

• Add a "deep search" option to the ModLoader Options.
• Add a "depth" option to the ModLoader Options defining how many levels deep the mod loader should search for zip files.
• Keep the steam_workshop_enabled option and make it essentially a preset that calls the new method with the right parameters.
