Please add CC (Closed Captions) download support for Netflix

I've been evaluating Keeprix and noticed that while regular subtitles download fine from Netflix, CC (Closed Captions) tracks are not downloadable at all.

CC is especially important for accessibility and for viewers who rely on sound effect descriptions and speaker identification. It would be great if Keeprix could support downloading CC tracks just like regular subtitle tracks.

This is actually a key factor holding me back from purchasing — if CC download support were added, I'd be ready to buy. I hope the team can look into this. Thanks!
