Ported the fabric version to NeoForge

Bug fixes

• Fixed a bug that caused an overflow error caused Pokemon to get deleted. Sorry about that.

Changes

• Added error handling to prevent overflow error. Tells you if you have enough space or not.

• Dynamically adjusts to your defaultBoxCount in your cobblemon config. GUI dynamically updates too. Please set this to 50 in your config for best results.

• Removed rename boxes GUI element. Not possible in 1.6.1.
