MAKE ALLAYS FIRE PROOF

Allay are awesome mobs, that are great to pick up apples from trees, and arrows from far away skeletons. But we need to bring them to more dangerous places, like the nether, and deep caves.
If the Allay would be fire proof, them we could bring them to more places, and they wouldnt care to fly on lava, as they already do now and die, its not the player fault, its them, so protect them, that way we bring them to more places!
