FFL Trinkets Compat

This is a simple compatibility mod made to fix an issue between Trinkets and FallFlyingLib (and any mod which uses the library) which makes Elytras being used in the Cape slot not working due to an incompatibility between Trinkets' Mixin and FallFlyingLib.

If you have FallFlyingLib and Trinkets installed, this fixes the vanilla Elytras not working.
