There are 5 possible outcomes:

    * No highway=bus_stop, but there is a naptan:AtcoCode => naptan that
      is not on the ground (green bus with X over it)
    * highway=bus_stop and naptan:verified=no => not yet checked (red bus)
    * highway=bus_stop and no naptan:AtcoCode => real stop not in naptan
      (blue bus)
    * highway=bus_stop and naptan:verified != no and note=* => stop
      checked with a problem, such as bearing wrong (cyan bus)
    * highway=bus_stop and naptan:verified != no and no note => stop
      checked and OK (green bus)

This suits the data I have and the way I want to use it, i.e. find stops 
to check then show others the stops that don't match their NaPTAN data 
for whatever reason.
