Ender Link System

[mikerooni]

The new Ender Link system, expanded with some new features (controllers, item transfer capability, multiple tiers, etc.).

ToDo List:

• Add ender fluid link cover, controller multiblock (with tiers) and linking card
• Add ender item link cover
• Add editable UI to the covers and controller / rework prototype UI
• Implement connecting covers to controller (also match controller UUID, stored on linking card)
• Implement virtual item & fluid transfer (proxy the storage of all covers on that channel)
• Implement linking multiple controllers (ensure that 2 channels are available per new controller in the network)
• Add multiple tiers for the covers
• Implement computing integration when 2.7 is merged
• Implement cross dimension networks
• Recipes and balancing
• Documentation

More TODOs as of the last push:

• Add linking cards to drops on both covers and controller
• Fix cards not being loaded initially (currently needs reinserting the card to be loaded, probably because of @Persisted handling)
• Check if it's possible to make TransferType a registry instead of an enum
• Consider transfer rate limit (requires moving the transfer logic to the controller and/or rate limiting the cover's returned transfer)
• Implement channel selection in cover UI
• Adapt channel count & range to tier
• Implement range restrictions between controller and covers
• Implement filtering
• Add remaining tiers for controllers

• Potential rework necessary for ProxiedTransferWrapper and transfer logic to better support IO type BOTH

Possible implementation - Transfer in two distinct steps:

1. Move everything from IO.IN to IO.OUT and then IO.BOTH
2. Move everything from IO.BOTH to IO.OUT only

LGTM currently, lmk if you want approval (lots of merging we'll have to do lolol)

I'm closing this one for now - in favor of starting over, if I work on it in the future ^^

Additions to revisit and possibly add to the current codebase:
