Title: Ignoring extensions in GPX

Temporarily ignoring extensions in a trkseg in GPX.

From the spec
```
Allow any elements from a namespace other than this schema's namespace (lax validation). [0..*]
```

I could write something that would allow users to pick and choose out of extensions what they want, but for now this is a waste of time.
