Elytra Contrails Mod

-- Elytra Contrails 1.4.7.3 for 1.21.1 -- 1.21.1 Backport! Experimental. -- Changes from 1.4.7.2:

• Restored first person trails functionality (This is kind of a "hacky" fix, if issues are occuring disable "forceHiddenEntityRenderPass" in the config json)
• Improved translucent trails, no longer over-writes water while rendering, better glowing trails (looks more like 1.21.11+ Elytra Contrails). Still over-writes clouds though unfortunately
• Restored snapping trail to wingtip functionality

Known issues:

• if you fly too fast you will start flickering becuase of a vanilla bug, and this will cause your trail to disappear. use Debugify if you want to prevent this from happening

• Particle selection no longer works
