TCX cadence does not import into Strava

[dkbarn]

Something about the way that RunnerUp stores cadence information in its .tcx file format is not compatible or recognized by Strava because the cadence does not appear in the resulting activity. However, exporting the same activity from RunnerUp using .gpx format does carry over the cadence data when imported into Strava.

Format is as specified by Garmin (same as from Garmin Connect too what I see), but Strava does seem to interpret this differently, at least in exports. GPX could be used in the export, but laps will not be included then.
