Some mods, namely Ears, expect ArmorMaterials to have ArmorMaterial.Layer for them: unascribed/Ears#169

I have a fork of Ears that should prevent crashes but in my opinion it would be better to have Ars Elemental armors simply have a Layer like Ars Nouveau armors do: https://github.com/baileyholl/Ars-Nouveau/blob/main/src/main/java/com/hollingsworth/arsnouveau/setup/registry/MaterialRegistry.java#L57
