all EntityArguments have been told to ask the server for completions
when if this was fixed on the client, that wouldn't be needed.

Subject: [PATCH] Properly resend entities
This resolves some issues which caused entities to not be resent correctly.
Entities that are interacted with need to be resent to the client, so we resend all the entity
data to the player whilst making sure not to clear dirty entries from the tracker. This makes
sure that values will be correctly updated to other players.
This also adds utilities to aid in further preventing entity desyncs.
This also also fixes the bug causing cancelling PlayerInteractEvent to cause items to continue
to be used despite being cancelled on the server.
For example, items being consumed but never finishing, shields being put up, etc.
The underlying issue of this is that the client modifies their synced data values,
and so we have to (forcibly) resend them in order for the client to reset their using item state.
See: https://github.com/PaperMC/Paper/pull/1896

Subject: [PATCH] Optimize Hoppers
* Removes unnecessary extra calls to .update() that are very expensive
* Lots of itemstack cloning removed. Only clone if the item is actually moved
* Return true when a plugin cancels inventory move item event instead of false, as false causes pulls to cycle through all items.
However, pushes do not exhibit the same behavior, so this is not something plugins could of been relying on.
* Add option (Default on) to cooldown hoppers when they fail to move an item due to full inventory
* Skip subsequent InventoryMoveItemEvents if a plugin does not use the item after first event fire for an iteration by tracking changes to the event via an internal event implementation.
* Don't check for Entities with Inventories if the block above us is also occluding (not just Inventoried)
* Remove Streams from Item Suck In and restore restore 1.12 AABB checks which is simpler and no voxel allocations (was doing TWO Item Suck ins)
