Get audio first when downloading DASH media

Browse Source 
The reason is twofold: audio data is usually smaller (more "dense",
i.e. has a higher bitrate), and often more important than video data
(e.g. when downloading talk show episodes). A partial audio download is
therefore usually more useful, as in the same amount of time youtube-dl
could capture a larger timeslice of a more valuable part of the media
stream.

All of this matters little for a completed download, of course.
