NestedShulkers

This plugin lets you store Shulker Boxes inside of other Shulker Boxes.
Infinite storage within a single block.

Note: This plugin is potentially destructive.
The ramifications of an item that can store infinite items are unknown.
It may become necessary to limit the nesting depth to prevent breaking.

On the other hand, if you find an approximate limit, please let me know.
That would be really cool information.

The plugin works by generating a temporary chest for each box when they are opened.
Once all viewers leave the temporary chest, the contents are saved.

Requires Kotlin and ProtocolLib
