Undespawnable Named Items Datapack

This datapack allows Item Entities to not despawn in the world if the item is named.
Special thanks to Xisumavoid for providing the idea for this datapack!
(Note: if you are using plugins that delete entities such as ClearLag this datapack may not work as intended.)
