Add an SEI message to an access unit.
Will add to an existing SEI NAL unit, or create a new one for the message if there is no suitable existing one.
Takes a new reference to payload_buf, if set. If payload_buf is NULL then the new message will not be reference counted.

Iterate over messages with the given payload type in an access unit.
