Cached chunk packets

After a chunk is requested into a packet i cache it for later. This system is prone to breaking if the synced registries for each player aren’t the same but im hoping to make sure they are the same. (I also want to precompute these and or cache them)
I experimented with a bunch of precomputing and caching and seemingly for now just saving the packet data after computing it once on load seems to work just fine for me right now
