Subject: mp_image: add some helpers

This is really basic for planar image data access; not sure why there
weren't such helpers before.

They also handle trickier formats that use bit-packing, or they would be
mich simpler. (This affects only BGR4/BGR4/MONOW/MONOH, I hope whoever
invented them is proud of triggering so many special cases for so little
gain.)
