This is a reland of 404be7f302
It adds support for reading .yuv files as well to not break anything.
Original change's description:
> Add Y4mFileReader
>
> Encapsulate logic for reading .y4m video files in a single class. We
> currently have spread out logic for opening .y4m files with partial
> parsing. This CL consolidates this logic into a single class with a well
> defined interface.
