draw sidewalk corners for pairs of just-sidewalks

The resulting geometry is not great sometimes, but this is still an improvement over failing outright. #243 tracks doing something better. Right now, the generalized trim-to-corners algorithm looks for collisions between adjacent pairs of road-edges. We also have cases where one road edge intersects the perpendicular of an adjacent road (both edges). One way to handle it might be an existing TODO in the code, "If there's no hit, consider extending both lines and seeing if they hit"
