DISCLAIMER: This is a fork of the original XL Packets mod, This fork extends the packet limit to the Java Integer limit

Fixes https://bugs.mojang.com/browse/MC-185901 by raising the packet size limit from 2MB to 2.14GB (2147483647), so that servers with large datapacks, packets, etc don't kick the client. This mod is needed clientside for any connecting clients.
