[Feature Request] Add Option For Preferred Audio Track

[gigapixelguy]

Some videos have multiple audio tracks on youtube For example: https://www.youtube.com/watch?v=Zp986RMLBD0 https://www.youtube.com/watch?v=tnTPaLOaHz8

This would probably be beneficial for international users.

For example when this feature is enabled one user can request fallback of audio in the following order:

1. Portuguese
2. Spanish (Spain)
3. Spanish (Latin America)
4. Spanish
5. English
6. Default (what is played by default)

It will select them in order present (meaning if 1 is absent it will select 2 if it is present and so on)
