Gothic Armor Trim

I retextured the flow armor trim and made netherite more purple, to match with the netherite from the Gothic Tools texture pack I made! I also wound up retexturing the elytra, and the elytra items, because why not?

I did not go so far as to retexture the netherite ingot, netherite armor items, and netherite armor trims, because the trims were chaotic enough as it was.

The trim that was picked for retexturing in particular was Flow, as it already looked gothic. I hope you enjoy!

Patched, now supports backporting.

Issues may arise as you find out that Flow didn't exist pre 1.21, though, but everything else is fully functional now.
