Add Armor Trims to Elytra

I think it would be really cool if we could put armor trims on Elytra.

Elytra are already a really important part of the game, but there's not really much you can do to customize how they look. Being able to use armor trims on them would make them feel a lot more personal.

You could use a Smithing Table with an Elytra, a trim template, and a material, just like with normal armor. The trim would appear on the wings, and the material would change its color.

It wouldn't change how the Elytra works at all. It would just be a cool way to customize them.

I think this would be a pretty simple addition that would give players a lot more ways to make their Elytra look unique.
