Memory optimizations (#505)

Browse Source 
* Remove LocatedBlock overhead in LBL map

* Add new space-efficient block map, with thourough testing

* Drop ordering property, add full insertion test

* Add licenses

* Fix mocked platform conflicts

* Disable full block map testing for faster builds

* Re-implement BlockMap with fastutil maps

* Re-write chunk batching to be memory efficient

* Make MultiStageReorder use BlockMap

* Increase LBL load factor, fix long-pack limit detection

* Fix infinite loop in chunk batching

* Save memory in history by cleaning up MSR

* Re-implement LocatedBlockList in BlockMap

* Fix data race with BlockType lazy fields

* Make IDs ALWAYS present, only runtime-consistent. Use for memory efficiency in BlockMap

* Remap inner structure of BlockMap for smaller maps

* Remove containedBlocks fields, not very efficient

* Fix minor de-optimizing bug in stage reorder

* Make long packed y signed

* Add extended Y limit configuration option

* Add licenses

* Store 3 ints for unoptimized BV list

* Add final to BitMath

* Correct int-cast for long-packing
