Fix increase(Infinity) to now set count=Infinity instead of maxPileSize

Infinitely-sized piles now can be transferred in inventories as you
would expect, creating another infinitely-sized pile, instead of trying
to fill up the entire inventory with multiple maxPileSize piles.

Closes https://github.com/deathcap/inventory-window/issues/24

This may need to be revisited if only finite pile sizes are desired,
perhaps with per-item-type limits (ref GH-2)
