Human Text Timestamping

Two APIs are used:

• API add() send audio to nexiwave engine, along with humanTranscription field (or humanTranscriptionFile)
• Wait for the timestamping to finish, or listen for the "TIME_STAMPING_DONE" message from your HTTP server
• API getTimeStampedHumanTranscription() to obtain the time stamping result.
