This is a pretty tiny update with very little changed. Recommended to update
from 1.16.2 ASAP as 1.16.2 is now no longer supported.
Plugins should mostly remain working as the NMS revision did not change.
Removes synchronization from sending packets
Makes normal packet sends no longer need to be wrapped and queued like it use to work.
Adds more packet queue immunities on top of keep alive to let the following scenarios go out
without delay:
- Keep Alive
- Chat
- Kick
- All of the packets during the Player Joined World event
Hoping that latter one helps join timeout issues more too for slow connections.
Removes processing packet queue off of main thread
- for the few cases where it is allowed, order is not necessary nor
should it even be happening concurrently in first place (handshaking/login/status)
Ensures packets sent asynchronously are dispatched on main thread
This helps ensure safety for ProtocolLib as packet listeners
are commonly accessing world state. This will allow you to schedule
a packet to be sent async, but itll be dispatched sync for packet
listeners to process.
This should solve some deadlock risks
This may provide a decent performance improvement because thread synchronization incurs a cache reset
so by avoiding ever entering a synchronized block, we get to avoid that, and packet sending is a really
hot activity.

* 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.
