Unable to remap class if two parents contain methods with same mapped name but different intermediary names

[CoolMineman]

If a class extending Item implements ToolMaterial and overrides getEnchantability it creates the following error when compiling in loom. This is because Item's getEnchantability is method_7837 in yarn and ToolMaterial's getEnchantability method_8026. Maybe tiny-remapper should dupe the method and warn?
