Copper Golem Sorting Efficiency Increases as they Oxidize

Copper Golems are a fantastic new addition to the game, and completely revolutionize item sorting. However, what if they got smarter and "more experienced" at sorting as they oxidize, but also become slower as they do so, too? The idea with this is that Copper Golems could store up to 10 chests in their memory, then remember the chests that they've already looked in so that they can more directly place items within the correct chest without wasting a bunch of time looking around in the wrong chests. Normal, unoxidized Golems would still function identically to how they do now, with each tier of Oxidization making them slightly better at remembering each chest they've seen up to the fully oxidized version which already knows items in chests prematurely.
