Module convert_osm::split_ways

Functions

dedupe_angles
should_collapse_roundabout	Many “roundabouts” like https://www.openstreetmap.org/way/427144965 are so tiny that they wind up with ridiculous geometry and cause constant gridlock.
split_up_roads	Returns amenities and a mapping of all points to split road. (Some internal points on roads get removed in this call, so this mapping isn’t redundant.)
