Support for upgraded Shulkers.

Please describe why you want this feature.
Well, quick shulker has already implemented native support for upgraded shulkers mod. As it stands, unlike the one I see commonly requested- the shulkers in upgraded shulkers don't use a multiple page format and don't stack when empty- So I'd assume this would also make it much easier to implement than the alternative. On top of being a widely used mod at that.

In a way, adding compatibility to this mod would be the same as if you made an entire back-pack mod with multiple upgraded levels.

I'm closing this- as it'd seem that reinforced shulkerboxes would be the one I'd also like. As upgraded shulkerboxes is not compatible with shulkerbox enchants but reinforced is.
