Real chunks decoded & rendering!!

I have managed to decode a bunch of chunks!(pictued is a 3x3 area rendered because of a 5x5 area thats loaded)
I still have set the blocklight and skylight to all 15s and i will probably need to go and fix that in a bit later, but for now it just copies over the palette from the global block state palette, copies over the longs for the biome data + palette.
For the most part it just copies over the nbt data into bytes and packages it up. It also makes up data, like it also says theres 16^3 (the maximum) blocks in each subchunk. This is to prevent it from unrendering when breaking stuff

Todo:

I want to load a bunch more chunks to make it more seamless
I want to properly give the lighting data, but ill do that later as it works fine for right this second
I want to make sending synchronized registries faster and possibly cache the packets that send them
