Ella Pietraroia 222864108f making a time based psi method for when to send packets 
Added a case that allows packets to be sent by unit of time (in seconds) rather than by number of packets or nal methods. Also made a variable that can be changed in vidgrinder to choose the amount of time, called PsiTime

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.

Added H264ID and H265ID consts and added logic to select this const for use in encoder based on mediaType param in NewEncoder. Also now
declaring PMT in NewEncoder so that we can set streamID correctly based on mediaType.

Saxon f59879b51d revid: removed ringBuffer after lexer 
Now that we want buffered senders (as required), the ringBuffer that was after the
lexer has been removed. Instead, we now have an ioext.multiWriterCloser to which the
lexer writes to. This then writes to the encoders, and then encoders write to each of
their own multiWriteClosers, which write to the appropriate senders. We now call
close on the first multiWriteCloser to close down the entired pipeline, as this close
call propogates through each level.

We have removed the outputClips routine as it's not required anymore to get data
from the revid ringBuffer, and have removed other things that were used by this, like
the IsRunning function.

We have also updated tests to work with these changes - they are passing.

Trek H 634ecfdbb2 mts: Limited size of encoder writes and updated audio_test 
Previously the encoder would not care if a write was given that exceeded the max PES packet size
because we were never using PES packets bigger than a frame of video. Now I have changed it so that
the encoder will check the write length and create a new PES packet if needed.
I have also restructured my test so that it can extract the data from PES packets that span accross multiple
MTS packets.
