This is not all of it as it is not possible (or at least I do not know
of a way) to get all suggestions for a repo/project. Did this via loop
searching mainly and taking the modernize suggestions.
* Thottle the publisher data channel sending when subscriber is slow
Avoid the publisher overwhelm the sfu data channel buffer when
the subscriber has lower receive bitrates. It will drop message
if the subscriber is considered too slow to block the entire room.
* Enable nack in mediaengine and disable it in transceiver as need
pion doesn't support per transciver codec configuration, so the nack of this session will be disabled
forever once it is first disabled by a transceiver.
