Regenerate all data. Implications:

- new osm2streets default lane widths
- some big duplicate osm.pbf input files, now that we never clip a
  boundary near a Geofabrik boundary
- most maps are still clipped to an old Geofabrik boundary, because the
  .osm file was still around
- downtown Seattle starts infinite-looping for blockfinding (will fix
  later)
- hopefully a large class of geometry crashes go away, because
  serialized geometry matches the original in-memory version (see #1061)
