Fix Incomplete Interoperability With Quickshulker

[Meshiest]

Before this change, the bundling feature of quickshulker deleted items after the 27th slot because the default behavior depends on UpgradableShulker and assumes all shulker boxes are 27 slot inventories.

This PR implements that interface and fixes that bundling issue.

Thanks!

Upon careful consideration, it seems that this mod should not rely on the interface of the shulkerutils, as it allows for gameplay even without the quick shulker mod. need to revert for now and organize the issues.

Ah sorry about that. I forgot about the mod actually needing to be there to provide that functionality. Thank you for taking the time to review my changes.

I see two paths for fixing this:

• on this mod's side: embed the shulker utils library that quickshulker uses
• on quickshulker's util lib side (similar to changes I made for drops-into-shulker and simple-shulker-preview): create a mixin to look at .inventory.size() as .getInvSize() + creating a temporary ShulkerBoxBlockEntity via item.getBlock().createBlockEntity().getInvSize()

[Aton-Kish]

I would like to avoid the former as it could potentially disrupt the release cycle. I prefer the latter. Since ShulkerBoxBlockEntity has a public method size() that represents the size of the inventory, I believe don't need a mixin. like ((ShulkerBoxBlockEntity) item.getBlock().createBlockEntity()).size()

Should https://github.com/kyrptonaught/shulkerutils/pull/1 get merged and kryptonaught updates quickshulker, the issues will be fixed!

Thanks for the feedback about ShulkerBoxBlockEntity.size(), I've made PRs to drops-into-shulker and simple-shulker-preview to address my error.

QuickShulker did not update, there is a fix for this issue?
