TL;DR
Make Radars Have an Option to Send a Signal When They Detect an Enemy Structure in the Scanned Chunk.

What?
It's a small thing but I think adding a circuit network option to send a signal when a scanned chunk has a biter nest in it it would be a good idea for managing artillery wagons in the late game.

Why?
the solution I currently have is to just send the artillery wagons after a specified amount of time. If the radars had that as an option, I'd just feed that into into the train station connected to it to make the artillery train arrive. I imagine there might be some other use cases for controlling biters or pentapods but I can't think of any good ones right now. It would give it more reason why the radars are grouped together with all the other military items. Like they're used for detecting enemy activity in the area that they can scan, so maybe they could be useful for PvP.
