ProtocolSupport

Updated to 1.16.5
Added compatibility with java 16

Fixed following bugs:
1) Weather inverted on < 1.7
2) Scoreboard prefix team color injection inserts 2 resets instead of 1 on < 1.13.
3) Item cooldown not displaying on non latest version.
4) Unable to modify books in non 0 hotbar slot on 1.13-1.16.3.
5) Chat hover action show entity not working on non latest version.
6) Translatable components translation not translating extra components
7) Varlong read as int

Implemented following changes:
1) Normalization of chunk data bits per block value. Bits per block values less that 4 is now treated as 4, values above 8 are treated as global
2) No longer map chests to enderchests for < 1.13 (this will make chests close to each-other not render, but that is preferable to not being able to break them)
3) Improve legacy potion mapping (now uses specific bits to parse type and properties instead of hardcoded ids)
4) Support custom biomes mapping (uses first legacy mapping if manual mapping doesn't exist)
