Need a command to list a streams available audio and subtitle options

[StephanieSunshine]

Describe the bug
I have been noticing a pattern where I can't seem to make crunchy-cli download a stream due to a misconfiguration with the audio or subtitle options. The most recent example of this is Gurren Lagann where I'm trying to pull my usual Japanese audio with English subtitles and I cannot come up with a working configuration. If you check out the url itself you'll find Japanese audio with English subtitles are available.

I feel if there was some command to be able to see the available audio and subtitle options it would make it a lot easier to debug and resolve the situation.

To Reproduce
Steps / command to reproduce the behavior:

$ crunchy  download -s en-US "https://www.crunchyroll.com/watch/GR751WEKY/bust-through-the-heavens-with-your-drill"

Expected behavior
Download the respected ts file to the local directory.

This is what a potential search command would do too (#20).

Closed in favor of #20.

Just as a note if anyone else reads this, I managed before #20 was selected to use the latest yt-dlp command with --list-subs to actually get a printed list of subs. I believe ( I saw this with Your Name ) that if Crunchyroll only has one audio track and one subtitle track, that it hard encodes the sub. I verified this with Your Name, as playing it in the browsers wouldn't let me turn the subs off. I just checked Gurren Lagann using the yt-dlp subs lookup and it looks like it is the exact same way ( hard coded audio and subs, yt-dlp reports no subtitles available ). The way I've been able to figure out if they are hard coded is to go into the browser and try and turn the subs off. If you can't turn them off, then it seems because it is hard coded.

I just tried to pull Gurren Lagann using the crunchy-cli 3.0.0-dev.8 (a6bfe0b 2023-03-09) build without an audio or subtitle flag and I keep getting a crash that is probably related to something else. Using yt-dlp to pull Gurren Lagann ended up with hard coded subs and Japanese audio. Playback worked as expected.

For completeness, below is the error I'm seeing from crunchy-cli
