Feature Request: Manually fix road snapping

[Nugman]

Sometimes when GPS signal is bad the track is snapped to the wrong road.

In this example I drove the same road forth and back. The road is in a narrow valley so I suppose the GPS signal isn't very good.

I would love to see a feature where the track can be fixed manually e.g. by dragging around position records similarly to the routing in Komoot.

The problem with the snapping to wrong roads is, that the portal is showing results for streets where acutally no measurements have been taken but the route has been snapped to by error.

Example: https://portal.openbikesensor.org/map#14.84/50.14023484761194/8.38078024226241

I never drove on the streets (paths/trails) marked with an arrow. The data was recorded on the main road (B455) only, but was counted for the small roads due to bad snapping.

For debugging purpose here's the CSV track from the first image:
