Change flexfec header reader to parse according to updated RFC.

This change changes the flexfec header reader ReadFecHeader function to parse the FEC header according the the updated RFC. The fec_packet argument is expected to have the protected ssrcs list already populated, as they should be retrieved from the RTP header.
Updated and added Reader unittests. Unittests that are relevant for the Writer, were put inside a comment. In the next change set, when the header writer will be updated, we will update the unittests accordingly.
