Maintenance update to support the version tracking change present in BigDoors 0.1.8.64

Removed

• BigDoors startup version check
  • This startup check was used to reduce bug reports as BigDoorsPhysics originally required a very up to date version of BigDoors. However this check broke recently in the latest BigDoors update and after reviewing it I have determined BigDoorsPhysics has aged out of needing such a startup check.

Updated

• Build against ProtocolLib 5.3.0

A quick maintenance release to support 1.21

Fixed

• 1.21 version parsing

Added

• Add support for MC1.20

Added

• Support for Java 11, thanks @MiroSneeball for the suggestion

This release marks the beginning of more version support for BigDoorsPhysics, with the plan of eventually supporting all versions of MC that BigDoors does.

Added

• Spigot support, thanks @MiroSneeball for the suggestion
  • Note: Spigot lacks the TeleportFlags api of Paper so shulker based collisions will fall back to the 1.16.5 -> 1.18.2 method
• 1.16.5 support, thanks @MiroSneeball for the suggestion
  • For now it is only 1.16.5, not .1 -> .4 this will be expanded in future
