Create standalone ramps for ramping between plateaus, optimizing for least digging effort.

When the ramp generation runs out of room due to the mining zone area, could you have it turn left or right? Think of stairs. You might go down a few steps to a landing, turn 90 degrees, then go down the rest of the way. I do this all the time. This way, I can keep my zones smaller.

Turning ramps are on the roadmap
