Add cache to quarry

Adds a cache to the quarry in order to reduce load and send larger stacks through pipes instead of just single items. Coin tossing ensures the cache gets purged around every 200 seconds. The interval isn't fixed in order to prevent material spikes from multiple quarries which got loaded simultaneously. When the cache is full, or the quarry finished, it is purged too.
