Audio cover preview support

[Gaesa]

Please describe the problem you're trying to solve

Without the proposed feature, the current state of audio file navigation in the application is not as intuitive or visually engaging as it could be. Users are only able to view metadata, which may not provide enough visual cues to quickly and easily identify specific audio files. This can lead to a less efficient and enjoyable user experience, especially for those with large collections of audio files with cover art.

Would you be willing to contribute this feature?

• Yes, I'll give it a shot

Describe the solution you'd like

The proposed solution involves checking if an audio file has a cover using the lofty library in Rust. If a cover is present, it will be used for the preview. If not, the program will fall back to previewing the audio's metadata. Here is a sample code snippet demonstrating this:

use lofty::file::TaggedFileExt;
use lofty::probe::Probe;

fn audio_has_cover<P: AsRef<Path>>(path: P) -> bool {
    return match Probe::open(path) {
        Ok(p) => {
            let tagged_file = match p.read().ok() {
                Some(file) => file,
                None => return false,
            };
            let tag = match tagged_file.primary_tag() {
                Some(tag) => tag,
                None => return false,
            };
            tag.picture_count() > 0
        }
        Err(_) => false,
    };
}

If the audio file has a cover, the following ffmpeg command can be used to generate the thumbnail:

[
    "/usr/bin/ffmpeg",
    "-i",
    audio,
    "-an",
    "-vcodec",
    "copy",
    thumbnail_path,
]
