More Supply Stockpiles V1.1
Adds supply stockpiles that hold 12 pallets per tile in 3, 2 and 1 tile sizes. The 3 tile one in a straight and corner version.
Left the corners free both because 36 is the maximum a stockpile can hold, for the 3 tile version that comes to 12 pallets per tile, and because it looks better with the poles of the resource conveyors.
Not sure about wether smaller stockpiles should be reserached when the large stockpile is available immediately, but for for now you have reseach ‘High Capacity Stockpiles’ to unlock them.
