Entity: Lane balancer

[thesixthroc]

The internal 1x1 Lane splitter entity was added in Factorio 2.0. If fed a single-lane input, it distributes that lane across both output lanes, balancing them. However, for a full two-lane input AB, it just transposes the lanes to BA.

I haven't seen a mod make use of it, and I believe that's because it neither cleanly mixes nor swaps the lanes.

There is a closely related entity I think mods would use (in particular my mod has a need for it): a 1x1 Lane balancer. I imagine it could work by swapping between mapping AB->AB and AB->BA when one or more items pass by. It could use the same graphics as the Lane splitter.
