[Suggestion] Upgradeable Inventory Space

[carstorm]

Although the mod is great I don't really use it since its better space wise to use the iron chests, metal barrels, or compact chests (which also allows custom colors and inventory sizes) mod for the large inventories and just put a sign on the chest. It would be great if this mod had an inventory upgrade for the quartz chests that would, as the name says, allow the user to expand the inventory space the quartz chests have.
