Refactor World-Management and Region/Chunk-Loading (#496)
* 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
