Optional fields are those which only occur sometimes. For example,

fields in optional RTP extensions only occur sometimes.

Add code for delta-encoding and decoding, to be used when producing
WebRTC event logs of the new format.

signed deltas or optional values yet. These will be added in
subsequent CLs.
