Current Chunk for Entity and Block Entities, counts by entity type This enables us a fast reference to the entities current chunk instead of having to look it up by hashmap lookups. We also store counts by type to further enable other performance optimizations in later patches.

Do not load chunks for light checks Should only happen for blocks on the edge that uses neighbors light level (certain blocks). In that case, there will be 3-4 other neighbors to get a light level from.
