Now correctly tagged as junction=circular because there are traffic lights and stop lines.

TODO:

- Traffic signal nodes need placing at the controlled intersections

- Check all the pedestrian crossings and islands, and get them StreetComplete-compliant

- Verify and place stop lines 

It's quite a daunting junction, and I want to make sure the traffic lights and stop lines are tagged correctly with an in-person survey before closing this note!
