Your Elytra automatically Equip/Unequip when you want!

[Features]
Simply keep elytra in your inventory and fly like normal. Your chestplate (and fireworks) will be automatically swapped to elytra, and re-swapped when you stop flying.
And this mod works completely-independent, no extra libraries requested!

[Warnings]
If you swap a previously swapped item, the re-swap may not work like you expected.
Even in this case, this mod will try to make effective swap as effective as possible, but I cannot guarantee that the results will be as expected.
Changing your hotbar selection causes no problems.
