LieOnLion/More-Chest-Variants#20

When using FastChest with my mod, More Chest Variants, it renders and extra chest always facing north, and double chests have two single chests.

Hi, two things need to be done.
On my side: adding something like https://github.com/FakeDomi/FastChest/blob/master/src/main/java/re/domi/fastchest/mixin/BlockEntityRenderDispatcherMixin.java#L28 to the BER dispatcher, I think I should add an API there.
On your side: something like https://github.com/4nner/IronChests/pull/20/files, adding explicit rotation models to your blockstates.
