Original issue's description:
> Fixed bug in ExtractFrameFromY4mFile API which was not extracting the frames correctly.
>
> Issue: This API was calculating the file_header and frame_header offset only for the first frame which is not the right logic. We need to skip the file and frame header every time we extract a new frame.
>
> Also added a unit test case which compares the extracted frame with the frame stored in text file.
