Conveyor Limiter

Conveyor belts currently always pull items at max speed. There are times you want to create a surplus, but only send some of that surplus elsewhere. The only way to do this today is to split the belt to your desired ratio, and then you have to scrap the excess to maintain the ratio, as the split alone wont reduce the belts flow if those splits have nowhere to go.

The cleanest option today is to split, send your surplus to a storage with a overflow splitter before it...and then still scrap the rest. Early game you can "fake" this with a splitter and assembler combo, but you can't reduce their input volumes once upgraded.

A belt limiter would function similar to a counter as a passthrough, but with a defined output amount (variable?). This would also allow you to potentially send items at odd intervals (like 45) without a network of splitters to split and rejoin amounts.

This would be most useful in modular builds, where you are producing <X> in a single location, and want to send a specific amount elsewhere, without rebalancing the line every time you add new locations.

It would also be extremely useful in late yellow+, if you're focused on maximizing voxel use by color, as shapes no longer use perfect 64x ratios, requiring an odd number of voxels per component. I build modularly based on the building, and try to keep as compact as possible to accommodate. This often means bringing in the exact right number of polycubes to get the job done.
