Disabling Sub Track should disable Mining from that track

[bpwhelan]

Is your feature request related to a problem? Please describe.
It's nice to have asbplayer setup with multiple subtitles (target language + native language) with native language disabled, so I can mine subtitles like usual, but open up the native translation in case i'm stuck on the meaning of a sentence.

The problem is when mining the target language, the native language is also often included in the mined sentence.

Describe the solution you'd like
Do not include disabled subtitles in Anki Exports, or have a config to disable this behavior.

Describe alternatives you've considered
Disabling Native Language subtitles. As of right now the workflow I was trying is not really possible since I have to go through and erase all the English from all the flashcards I mine while watching.

Additional context
I did a few searches in issues, but couldn't find anything. I feel like this would be a pretty popular workflow to increase the casual enjoyment factor of sentence mining.
