Saxon 90ab359599 codec/mjpeg: tidying up 
Separated my code from code that was ported from ffmpeg (differen copyright). Also added utils.go file to house the putBuffer and bytestream types. Reduced copying and use of bytes.Buffer.
Instead expanded putBuffer functionality so that I can use this throughout process (reduce copying from buffer to buffer).

Saxon e3b6d2101a Fixed bugs, now working 2019-12-23 14:24:08 +10:30
Saxon ba25cdfd12 codec/mjpeg/extract.go: wrote Extractor type 
Wrote extractor type that provides an Extract function to extract JPEG frames from an RTP/MJPEG stream and writes them to a destination.

Saxon c2ce700cbd codec/mjpeg/jpeg.go: added writeHeader function to write JPEG header 
This also included the addition of some lunimance and chrominance tables, a multiError type (implements error) and a putter type, that will put uint16s, bytes and "buffers" into a byte
slice.
