AudioStreamHandler ( audioDecoder , onSamplesDecoded )
The constructor that generates the decoder and handles routing callbacks
Signature 
Meta.WitAi.Requests.AudioStreamHandler.AudioStreamHandler(IAudioDecoder audioDecoder, AudioSampleDecodeDelegate onSamplesDecoded)
Parameters
audioDecoder: IAudioDecoder  The audio type requested (Wav, MP3, etc.)
onSamplesDecoded: AudioSampleDecodeDelegate  Called on background thread for every chunk of samples decoded.
