    webrtcsink: Add a mechanism for SDP munging
    
    Unfortunately, server implementations might have odd SDP-related quirks,
    so let's allow clients a way to work around these oddities themselves.
    For now, this means that a client can fix up the H.264 profile-level-id
    as required by Twitch (whose media pipeline is more permissive than the
    WHIP implementation).
