Add option to disable adding auto generated audio title metadata

In this example the player would default to playing the audio w/o a label until the metadata is added giving the user a bad UX because of the "Unknown" audio.

You're saying the player would select the stream without a title? But all streams would have a title. Can you elaborate a little more on this.

For someone who doesn't know what AC3 (or MP3) is, there's no need to add that to a label. They just want to know (if they want to know at all) what the language is.

This is user preference and for those that want to only know what the language is, they can just ignore the AC3 (6.0 Channel).

No, you misunderstand. The people that view the videos I am re-encoding are... well... not technologically inclined. If they see a label in the player that says "Unknown" for the audio I bet I get a phone call. (Think elderly parent.) At the same time I don't want to have that label include "AC3" "MP3" or anything else (ring, ring). The player will, if there is a language tag, and no title tag, just call it "English", but if there's a title tag it'll use that instead.

Long story short, I have to post-process all the converted videos and strip the title metadata manually.

If there is a already title, it is preserved. If there isn't, the title is added as shown above. If you want to remove the AC3 (6.0 Channel) section from the generated title you can edit this line.

I've forked the repo - I'll see about doing a pull request, but node.js isn't one of my goto languages.
