Add default method durationUs(long) in TrackOutput

Browse Source 
The method allows extractors to set track duration when available. The `default` implementation does nothing, allowing implementers of `TrackOutput` to override it if they need to handle track duration.

Implemented it in `FakeExtractor` to print track duration in dump files.
