Allow VideoTimingExtension to be used with FEC

Browse Source 
This CL allows for FEC protection of packets with VideoTimingExtension by
zero-ing out data, which is changed after FEC protection is generated (i.e
in the pacer or by the SFU).

Actual FEC protection of these packets would be enabled later, when all
modern receivers have this change.
