* Implement PackedIntArrayAccess * First working render with BlueNBT * Progress converting chunkloaders * Core rewrite done * WIP - Restructuring configs and world-map mapping * WIP - Compiling and starting without exceptions :) * Fix cave detection * Ensure configuration backwards compatibility (resolve dimension from configured world if missing) * Implement support for 1.16+ chunks * Implement support for 1.15+ chunks * Implement support for 1.13+ chunks and some fixes * Also find worlds based on their id again in BlueMapAPI * Improve autogenerated config names * Implement equals for all ServerWorld implementations * Get rid of var usage
