The optimizations in the last update didn't have the effect I expected under real world conditions. To fix this, I rewrote a significant part of the check and moved part of the code to the packet level. This time it was tested on a server with >50 players online, and this time the performance really is significantly improved.

Note however that this uses a specific ProtocolLib function that was made much faster about half a year ago, which means you should use a somewhat recent dev version or you will have worse performance.

The config file wasn't changed.

Changelog v0.14.2:
- rewrote part of the Reach check to fix performance issues
