Mass Storage Unit

There are four types of Mass Storage Units in the mod. They all serve the same purpose, that is, storing a large amount of a singular item in a single block. The block will retain the items inside in it when broken, just like crates.
Crafting
Tier 1
The first tier of mass storage unit can store 100 items, thus not being that helpful considering a chest can store many times more, it is however cheap to make, needing only an iron plate and some wooden planks.
Tier 2
The second tier of mass storage unit can store 10,000 items, that is 156 stacks and 16 items. It is able to store many more items than a regular chest.
Tier 3
The third tier of mass storage unit can store 100,000 items, that is 1562 stacks and 32 items.
Tier 4
The fourth and final tier of mass storage unit can store a massive 1,000,000 items, that is exactly 15625 stacks, however it comes at a fair cost.
Usage

Place an item in the middle slot of the GUI to set the type of storage (this item is not consumed), Items can then be placed into the top slot, shift clicked from the inventory, or inserted via automation to be stored into the unit. The two buttons underneath the type slot are for extracting items. Extracting items can be done either individually with the button on the left, dropping one item into the bottom slot. Or by activating the right button, which will attempt to always keep the bottom slot filled. Automation can only extract from the bottom slot, and only when it has items in it.
