Can we use EekoAddRawPath with raw video compression keyframes? #118

Digic 5 is known to have fast (hw accel?) operations on buffers. These ops include subtraction: https://www.magiclantern.fm/forum/index.php?topic=13408.0

We could subtract raw video frames from a keyframe (every x-th? The prior?) before compressing. This should compress better and could be restored perfectly in post. Would this overall be an increase in effective data rate?
