Support downloading a specific quote as audio or video.

[lightonflux]

Imagine you need a sound bite. Currently the workflow is as follows:

1. You run download for all the subs.
2. Then you search and find a quote that fits your needs.
3. Now you need to manually download the file with yt-dl. yt-dl <link> or yt-dl -x <link>
4. Next step is to cut the media file: ffmpeg -i <input file> -ss <ts> -t <duration> -acodec copy -vcodec copy <output. file>

A streamlined workflow could look like this:

1. download channel subs
2. search key words
3. Get quote id from listing
4. yt-fts quote-dl --audio <ID> to download sound or video bite. Maybe this needs a duration argument?
5. You find a file name <video-ID>-<quote-ID><Sanitized Quote>.mp3 (or similar) in your working dir.

Done. yt-fts would download the file as specified (e.g. via --audio or --video) and cut it to bits.

Is this something that is in scope of this project? Do any user users have this use case?
