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

Saxon 513e9d06ff container/mts: moved contents of metaEncode_test.go to encoder_test.go and deleted metaEncode_test.go 
The contents within metaEncode_test.go were strongly related to the contents
in encoder.go, so the code was moved and the file was deleted.

Saxon 2bd7a009ce container/mts: BytesForMetaInterval renamed to TrimToMetaRange and now returns Clip for similar reasons to previous commit 2019-06-15 02:12:17 +09:30
Saxon ceee163b74 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.

Saxon 12c205d75f container/mts: wrote test for Clip.Bytes and generalised logic for generating frames into genFrames func 2019-06-13 18:12:17 +09:30
Saxon 1323cbcae3 container/mts: filled Clip.Bytes 
writing Clip.Bytes required a change to the Clip type. The Clip type now possess a slice that
references the memory in which the Frames should reference for the media. Appropriate changes have
been made to Extract and TestExtract to accomidate this change.

Saxon 8f434e9703 container/mts: added payload_test.go and fixed bugs in Extract 2019-06-13 15:52:25 +09:30
Saxon b473451288 container/mts: added payload.go file with Extract function and types 
payload.go has been added which will contain functionality for dealing with MTS
payloads. A function has been added called Extract, which will return a Clip. Clip
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.
 2019-06-12 01:17:14 +09:30
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.

Saxon 482f5609e5 container/mts/meta: wrote test for GetAllAsMap 2019-06-11 22:15:27 +09:30
Saxon 9af964cfc9 container/mts/meta: added GetAllAsMap function 
This function is very similar to GetAll, except that is returns a map[string]string rather
than a [][2]string. It's become apparent that a map[string]string might be more useful in
some circumstances.

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.
