Wanting to put everything on your sushi belt and extract all the stuff you need with a single splitter? This sushi splitter filters all the items passed to it using the circuit network. Compatible with quality filters.
The splitter filters all circuit items with positive values.
The splitter fills both lanes, if the left lane is full, it will try the right lane and visa versa.
It's a unique entity, normal splitters are not modified, The item icon is visually different, but once it is built it looks exactly the same as a normal splitter.

Early version, help appreciated. Fork as you please. Please ask for ownership transfer if you'd like to actively improve this mod.
-- Bob's mod compatibility is prepared but Bob's Logistics doesn't support circuit connections yet.
-- Added item stacks support for space age in v0.1.2
-- Not tested with mega-factories. Impact on speed is unknown.
-- In-game the sushi splitter only shows 1 item, the thumbnail with four items is the magic of mspaint. Any good tips on how to implement this in-game are welcome.
