Some fixes to get the Arboretum trails connected.

- Grab fresh Seattle OSM, picking up https://www.openstreetmap.org/changeset/108071529
- Treat highway=footway, bicycle=dismount as a cyclepath, for now
- Treat service=driveway, bicycle=designated as a cyclepath

Since this requires regenerating all maps anyway, also include some
stuff to improve Aurora near Green Lake:

- stop making highway lanes super wide by default; they just make
  divided highways overlap themselves
- filter out service roads with access=customers

But note the bridge from the Arboretum to Lynn is still disconnected,
because of detailed footway mapping that isn't tagged as
bike-accessible.
