Update multiplex encoder to support having augmenting data attached to the video

Multiplex encoder is now supporting attaching user-defined data to the video
frame. This data will be sent with the video frame and thus is guaranteed to
be synchronized. This is useful in cases where the data and video frame need
to by synchronized such as sending information about 3D objects or camera
tracking information with the video stream

Multiplex Encoder with data is implemented in a modular way. A new
VideoFrameBuffer type is created with the encoder. AugmentedVideoFrameBuffer
holds the video frame and the data. MultiplexVideoEncoder encodes both
the frame and data.
