[1.21.1] Spirit Jar/Runestone Jar - item that allows to transport entities

[guide-for-you]

But also part of the "sacrifice the spirits of excess parent animals"

I was thinking on what can decorated pots used for,and one of the ideas was "Canopa"(yeah,same one as Ancient Egyptian one basically).Used for Twilight Grove to kind of store spirits of killed by binding them to this vessel for latter use.
