TrkSeg can be empty on GPX 1.1

[alex-piccione]

With a GPX 1.1 you have this error parsing a GPX file:
NullReferenceException
if the file contains an empty trkseg element ()

trkseg can be an empty element: http://www.topografix.com/GPX/1/1/#type_trksegType
(it is a complex element and contains a sequence of [0..*] trkpt elements)

The problem is in Gps\Serialization\Gpx11Serializer.cs

private static void ParseTracks(GpxFile xml, GpsData data)
[...]
foreach (var wptType in trksegType.trkpt)

trksegType.trkpt is null if trkseg element doesn't contain any point.

(problem exists in version 0.13 and 0.14)

A segment is added in track only for adding points, so it can be ignored if it hasn't points.
Proposed solution.
from:
foreach (var trksegType in trkType.trkseg)
to:
foreach (var trksegType in trkType.trkseg.Where(seg => seg.trkpt != null))
