MPEGTS Audio Descriptors

Added ability to add audio descriptors for mpegts output format.

Audio Component Descriptor

Identifies the type of component stream and may be used to provide a text description of the elementary stream.

Parameter	Description	Allowed Value	Default Value

Supplementary Audio Descriptor

Provides additional information about the audio streams which allows the receiver to present the appropriate stream, or mix of streams, to the user.
