* Limit dynacast to video and media loss proxy to audio
Was looking at keeping the track type out of those modules
and do a check at a higher level, but it is a bit unwieldy.
So, adding checks to the modules.
Also, ensuring that media loss proxy does not reset unconditionally
every second. Audio RTCP happens once in 5 seconds or so.
So, if server proxied let say 2% at t = 5, t = 6 would have
proxied 0 loss which may or may not be true. So, ensure that
a report was received and proxy value is updated by an actual
report.
