need a new only mp3 audio download feature

[GreninjaServer]

I would like to request a new feature for the yt-dlp-gui application. It would be great to have an option to download audio in MP3 format at 320kbps, with an embedded thumbnail from the video. This feature would be very useful for users who want high-quality audio files with metadata included.

Feature:
Option to Download MP3 at 320kbps: Allow users to select an option to download audio in MP3 format with a bitrate of 320kbps.
Embed Thumbnail: Embed the video's thumbnail into the MP3 file as album art.

would also be great if the "Split by Chapters" feature could be used to extract audio only instead of videos that need need to be post processed to extract just the audio from each chapter video, resulting in what is essentially an album of music tracks.

I made a telegram bot, just for that. tailored for mp3 with chapter selection, get audio a specific chapter.
