Fix distance calculation for GPX files without elevation data

Browse source 
Distance was only stored in the elevation profile array, which was
empty when track points had no <ele> elements. Now computed via
haversine independently and exposed as gpxData.distance.

Tested: berlin-dresden-radweg-2021.gpx (5660 points, no elevation)
now correctly reports 248.8 km.
