Optimize Light Engine 
Massive update to light to improve performance and chunk loading/generation.

1) Massive bit packing/unpacking optimizations and inlining.
  A lot of performance has to do with constant packing and unpacking of bits.
  We now inline a most bit operations, and re-use base x/y/z bits in many places.
  This helps with cpu level processing to just do all the math at once instead
  of having to jump in and out of function calls.

  This much logic also is likely over the JVM Inline limit for JIT too.
2) Applied a few of JellySquid's Phosphor mod optimizations such as
  - ensuring we don't notify neighbor chunks when neighbor chunk doesn't need to be notified
  - reduce hasLight checks in initializing light, and prob some more, they are tagged JellySquid where phosphor influence was used.
3) Optimize hot path accesses to getting updating chunk to have less branching
4) Optimize getBlock accesses to have less branching, and less unpacking
5) Have a separate urgent bucket for chunk light tasks. These tasks will always cut in line over non blocking light tasks.
6) Retain chunk priority while light tasks are enqueued. So if a task comes in at high priority but the queue is full
   of tasks already at a lower priority, before the task was simply added to the end. Now it can cut in line to the front.
   this applies for both urgent and non urgent tasks.
7) Buffer non urgent tasks even if queueUpdate is called multiple times to improve efficiency.
8) Fix NPE risk that crashes server in getting nibble data

Fixes #3489
Fixes #3363

Subject: [PATCH] Optimise random block ticking
Massive performance improvement for random block ticking.
The performance increase comes from the fact that the vast
majority of attempted block ticks (~95% in my testing) fail
because the randomly selected block is not tickable.
Now only tickable blocks are targeted, however this means that
the maximum number of block ticks occurs per chunk. However,
not all chunks are going to be targeted. The percent chance
of a chunk being targeted is based on how many tickable blocks
are in the chunk.
This means that while block ticks are spread out less, the
total number of blocks ticked per world tick remains the same.
Therefore, the chance of a random tickable block being ticked
remains the same.
