[feature request] CLI functions, print to stderr

[luphoria]

The scraper works great, and the TUI works fine, but it would be immensely useful if I were able to use searches in qobuz-dl programmatically, similar to yt-dlp's function.

i.e.

`qobuz-dl --search "The Beatles - Don't Let Me Down" --dump-json"

would return

[["The Beatles","Don't Let Me Down","lossless","235803329"],["The Beatles","Don't Let Me[...]

and I could then pass

qobuz-dl 235803329 --print-filename

and it would return

/path/to/qobuz-downloads/The Beatles - The Beatles 1967 – 1970 (2023) [16B-44.1kHz]/09. Don't Let Me Down.flac

Something like this. Stuff like json output doesn't need to be so robust but at least something I can parse!
