[Feature Request] Disable crate and key stacking

[ga6rielsilva]

Could you add an option in the box/key settings to not allow them to be stacked? Same as Totem of Undying, tools, armor and potions.

I would like them not to stack because I use these crates without a key, and the way I do this can create an imbalance in the game mode on my server.

Hey! In 1.21 (idk when exactly) you can change the stacksize of any item that has no durability from 1 to 99 Stacksize (in java every item type) so you can make a custom item with a custom stack size and replace them
