GPX file upload now supported

Intervals.icu expects to find power like this:

   <trkpt lat="-33.9361260" lon="18.4266640">
    <ele>85.0</ele>
    <time>2021-02-23T04:45:37Z</time>
    <extensions>
     <power>245</power>
     <gpxtpx:TrackPointExtension>
      <gpxtpx:atemp>23</gpxtpx:atemp>
      <gpxtpx:hr>101</gpxtpx:hr>
      <gpxtpx:cad>66</gpxtpx:cad>
     </gpxtpx:TrackPointExtension>
    </extensions>
   </trkpt>

I have added support for <gpxtpx:watts> (overrides <power> if both present) and will deploy Tues AM (GMT+2).

Awesome, thanks for answering and adding the support so quickly. I’d just about come to the same conclusion about the expected format through trial and error but you’ve saved me a job updating the tool my end :slightly_smiling_face:
