-MP3 Encoding

+### MP3 Encoding
     - Produces 1 or more mp3 files for the AAX title.  If you desire a single file use the --single option
     - If you want a mp3 file per chapter do not use the -single option. Note a m3u playlist file will also
       be created in this instance.
     - If you desire flac encoding. use the --flac option.  It's a bit faster but also a bit less compatible.

     - If you have a .authcode file available in the current working directory, it will read the first line of
 that line and treat it like your auth_code. When you do this you do not need to specify an AUTHCODE input.
