InstEnt

• Completely rewrote mod to be server sided
• Removed NBT data syncing as it was unnecessary
• Fixed a crash caused by client code in the teleport sync mixin
• No longer dependant on Fabric API

The client side interpolation removal caused more issues than it solved, and would commonly cause entity stuttering, especially on players with poor connections. All client side code was removed from the mod in favor of a smoother experience.
