Ignore gaps in annotated map matching results

[oxidase]

The map-matching option gaps=ignore is used in combination with timestamps use_timestamps && allow_splitting, but would be nice to ignore gaps in annotated map-matching results with a waypoints parameter.

For example, map matching request
http://localhost:5000/match/v1/drive/9.54358,51.47337;9.54396,51.46233;9.541360000000001,51.44117000000001;9.570640000000001,51.44753000000001;9.5922,51.44337;9.61096,51.44688000000001;9.611350000000002,51.44323000000001;9.621630000000001,51.439960000000006;9.624410000000001,51.429930000000006;9.631390000000001,51.42541000000001;9.63521,51.425650000000005;9.64521,51.41937;9.646130000000001,51.41819;9.644860000000001,51.414970000000004;9.64864,51.41489000000001

    }
  ]

and with waypoints=0;14 parameter the result is NoMatch.

A new behavior with parameters gaps=ignore&waypoints=0;14 will be a "loose" map matching with a routable part between locations 9.541009,51.441187 and 9.636801,51.426068 that does not correspond to missing trace points.
