Elevation treated as unsigned #31

29 introduces a new issue with dumping elevation data to GPX:

  <trkpt lat="…" lon="…">
    <ele>0</ele>
    <time>2019-10-23T12:10:05Z</time>
  </trkpt>
  <trkpt lat="…" lon="…">
    <ele>65535</ele>
    <time>2019-10-23T12:10:10Z</time>
  </trkpt>

Looks like the elevation field is interpreted as unsigned when read from the device.
