This change included a rename of IntraRefreshPeriod to MinPeriod, and the addition of the ClipDuration param. PSI are now written before IDR. Clips are no longer outputed
based on PSI but rather a time ClipDuration, where ClipDuration >= MinPeriod, however, PSI must still be at the beginning of each clip. Also created functionality to update
meta time even if we don't have a response to update.
