Add transcription_options to AudioInfo (#170)

* Add transcription_options to AudioInfo

It would be great if we can include the transcription_options in AudioInfo.

My application is only making a few changes but leaving the rest as default.
However, I would like to record down all settings (including those that I did not specify) so that the audio can be transcribed again identically in future if need be.

* Make TranscriptionOptions appear before AudioInfo

* Remove unnecessary whitespace
