acc codec support for audio export would be great

The fewer issues I have to read, the more new features I will have time to implement, so I ask that you please try these things first

• Check out all the menus and keyboard shortcuts. Maybe the feature already exists?
• Try with the newest version from GitHub
• Read the documentation and FAQ, Known issues, Troubleshooting to see if the feature already exists
• See if someone already suggested this under Issues or Discussions

Description

I tried discarding video tracks and cutting some audio files from a MP4 video only to find acc is not an export option and no codec support to re-encode as MP3, which I found really weird since Losslesscut can still extract the original audio track as an acc and I had other MP4 files exported into MP3 just fine for the last few years. Not a big deal, but I do work with acc occasionally and thought it would be nice to have proper codec support if it isn't too much of an hassle.
