Slotless Item Handler compat addition

[UnseenFaith]

When interfacing with other mods that read/use the contents of the storage chest/barrel, if the barrel or chest has stack upgrades, it seems that external interfaces can only read it as a single stack of items instead of the full size of the slot. Unsure if it happens with all stack upgrades, the ones I have been using are the netherite ones.
