Implement 'lightening' of NibbleArrays - only allocate buffers when non-trivial value Saving from 40-45% of memory use by chunk section data.

Finish up NibbleArray lightening work - use for Snapshots, reduce copies

Fix nibble handling with NBT - arrays aren't copied by NBTByteArray
Return LOHS to full operation.
Per world view distance.
Fix various crop growth modifier formula issues
Add OldChunkLoader from mc-dev for diff visibility

Optimize packet used to unload chunks for the client

At the moment telling a client to unload a chunk involves calling the entire chunk from memory, deflating it and then sending it through the pipes even though the client ignores it and based on the bitmap simply unloads the chunk, and to add the cherry on top, this is done on the main server thread.
Skip entity.move() if we are not moving anywhere.
Alternate, sync-free-but-safe chunk reference cache
Tick loop optimization - sleep for as long as possible.
