tests: add standalone program for VP8 parser.
Add standalone test application that demonstrates how to use the new VP8 bitstream parsing library, while also allowing simple debugging/ tracing of IVF files. [clean-ups, updated to new parser API] Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>
