Add option to export files in folder named "Title - Writer [ASIN]" format

[Rexadev]

or "Title - Writter - Narrator [ASIN]" or SeriesName/FileName

[audiamus]

The naming of files in the export folder is exactly the same as with the original Audible app for Win10. The purpose here is to provide full compatibility with AAX Audio Converter. So, it's by intention; any change here would break that compatibility.
