Disconnect Packet Fix

This release makes changes to the codebase that allows to build the mod for multiple different modloaders via Architectury - starting with Fabric and NeoForge!

There are no additional dependencies that are needed for the mod to function.

Functionality is largely unchanged. This update only concerns multi-modloader support.

NOTE: Fabric does not have an official 2.0.1 build, as the changes between 2.0.0 and 2.0.1 only concern NeoForge.
