Snow Under Trees (Fabric)

This update doesn't have any major changes, other than the configuration can now be found at snowundertrees.config.json instead of snowundertrees.json5 - old configurations will automatically be migrated to this new format.

• Refactored configuration screen using YACL.
• Restructured mod classes to be easier to maintain.
