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 c2ce700cbd codec/mjpeg/jpeg.go: added writeHeader function to write JPEG header

slice.

Ella Pietraroia c4d809be27 Filter interface take 2 
This branch was made because we were having problems with rebasing the original filter-interface branch. Filter-interface was used to make interface for filters and adding into pipeline made a new file (filter.go) that conatins package Filter. This package has the filter interface, with one filter, NoOp. More filters can be added. The filtering stage was placed inbetween lexing and encoding by changing the LexTo function to have the filter as it's destination and making the destination of the filter to be r.encoders
