revid: now have MinPeriod and ClipDuration params
...
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.

We have only ever used this function to find PSI so it makes sense to make it exclusive for this. It now also returns the streams found in the PMT. So that
we can actually retrieve the PIDs of the media and their types.

container/mts: BytesForPTSInterval renamed to TrimToPTSRange, and now returns a Clip

It was concluded that it would be more useful if a function that provided a data segment from
the original clip just provided a new Clip, i.e. useful things like PTS and meta is still
available in the segment. So, BytesForPTSInterval was renamed to TrimToPTSRange and now
provides a Clip. The test for this function was updated accordingly.

payload.go has been added which will contain functionality for dealing with MTS

is a type representing a sequence of media frames ([]Frame). Type Frame has been
added which represents a media frame. It provides fields to hold the media as
byte slice, PTS to hold the PES timestamp, an ID for identification of codec type
and finally the relevant Meta from the most recent PMT.

Added function to extract meta from first PMT found in a mpegts clip. This simply

then mapping metadata. Also added testing.
