Saxon 191be04b11 revid: added support for MJPEG packetisation 
Changes included adding support for variable InputCodec that may be set via netreceiver/vidgrind to set to H264/MJPEG. Also setting revid's lexTo
function to mjpeg.Lex in the case of an MJPEG InputCodec. Added options parameter to mts.NewEncoder function so that we can change options of the
encoder, namely whether it bases PSI interval on NAL type, or number of frames - in the case of MJPEG we based PSI interval on number of frames.

Saxon 817cc86a34 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.

Saxon ed11fac655 container/mts/mpegts.go: FindPSI now returns a map[uint16]uint8 containing program PIDs and their types instead of []psi.PmtElementaryStream 2019-08-06 15:38:34 +09:30

Saxon c55cd9a64e container/mts: wrote test for FindPSI and corrected bugs 
Wrote the FindPSI test which revealed a bug regarding creation of a PMT using comcast gots. This was fixed by writing Payload function and
extracting payload of PMT packet before giving to psi.NewPMT.

Saxon 0825799cfa container/mts/mpegts.go: renamed IndexPid to FindPSIs and change such that only looked for PSI 
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.

Saxon 3eab25e18b container/mts: added SegmentForMeta func and testing 
This func will further segment an MTS segment to each series of packets that
correspond to a given key and val of meta. Testing for this func has also been
written.

Saxon 1a233d8576 container/mts: wrote function TrimToMtsRange and added related testing 
This function will return a sub slice of MPEG-TS corresponding to an interval of metadata.
Also wrote testing for this function.

Saxon e4bce3bcb3 container/mts: added ExtractMeta function and testing 
Added function to extract meta from first PMT found in a mpegts clip. This simply
wraps the logic we've used in vidrecord, i.e. Finding the PMT, converting to a
comcast gots psi.PSIBytesm, using HasDescriptor to get the meta descriptor, and
then mapping metadata. Also added testing.

Wrote a test to check mts encoding of video to validate packet creation etc. Test is failing because how I did mts
encoding is interesting, thinking about changing.

Saxon a8aec484df container/mts: wrote test TestFindPid and corrected bug 
Completed test TestFindPid to validate function of FindPid func in mpegts.go. Through this
process, it was found that there was a bug in this func, whereby the returned packet was
not complete due to indexing issues. The bug is fixed and the test passes.
