Faster chunk conversion (#1400)
* BlockStorage is never used concurrently, no need to synchronize * initial, semi-functional, faster chunk conversion * faster chunk conversion works well for every situation except spigot * delete unused ChunkPosition class * preallocate and pool chunk encoding buffers * make it work correctly on spigot * make field naming more consistent * attempt to upgrade to latest MCProtocolLib * remove debug code * compile against my MCProtocolLib fork while i wait for my upstream PR to be accepted * return to Steveice10 MCProtocolLib
