USE IT AT YOUR OWN RISK, RESTORING THE CONFIG FROM 0 IS RECOMMENDED
This version can be considered as a BETA, I heavily tested it on my network but the real stability will come from customers reporting problems.

This version brings LPX to a very more powerful layer of protection, now LPX decodes packets ALSO before ViaVersion trying to avoid exploiters to abuse ViaVersion's lack of limit checks.

I worked so hard on this version since the work was also to edit PacketEvents in order to allow a clean and safe injection, I implemented tons of new Item checks, most of them for the modern versions and improved exception handling / kicking during critical moments, this is by far the most secure and advanced version ever created of LPX
