Expanded Storage

Likely the last release for 1.21.4 until I start working on implementing new features.

Oh and I might have broken the API surface with the refactors, if so I'm sorry!

• Restore IItemHandlers for NeoForge.
• Sync and fix NeoForge's REI plugin and sync its code with the Fabric version.
