Show full stack trace for errors during chunk caching/compression
Move exception logging to method body so we don't end up logging all outbound exceptions, which other plugins (cough ProtocolLib) may or may not be causing.

Also rumours this patch causes the server to break with ProtocolLib installed.

In short, there isn't actually anything wrong with the async chunk compressor, it just accidentally caused console logging of errors which were previously ignored.
This commit restores that behaviour

You may be asking yourself why we are completely ignoring any errors which come this far down the pipeline.
The answer is quite simple:
Mojang did it
The default Mojang pipeline doesn't have any ChannelOutboundHandlerAdapter or similar instances, and thus nothing to handle exceptionCaught
So when a channel.write() or channel.flush() fails, the error message is actually just passed straight to the future provided.
It is then subsequently discarded, the channel closed, and no one except the user was any the wiser it actually happened!
Unfortunately for us, the default exceptionCaught in this class sends a blaring warning to the server admins indicating that it couldn't send a packet to a disconnected user!
We don't care about these warnings, if we did something wrong to disconnect the user, it is already logged in the proper location, as are broken sockets
tl;dr no need to blare warnings on each write to a broken socket
Add warning when null chunk buffers are encountered - most likely due to the orebfuscator plugin.

Cap Entity Collisions

Limit a single entity to colliding a max of configurable times per tick.
This will alleviate issues where living entities are hoarded in 1x1 pens.

Refactor chunk compression to use its own thread pool in order to eliminate disconnect race conditions caused by Mojang's nasty disconnect routines.
Async chunk compression needs a little bit more work still, disable for now
