img2twit: prevent two points from having the same coordinates, since this
is forbidden by the image format; simplify operation computations by not
packing coordinates at runtime; add a version information in the file
format for future extension.

Another img2twit space optimisation: if we have remaining bits at the end

Tremendously improve img2twit.cpp: only compute the new error around the
updated pixel, compute bit allocation at runtime, weight operations in
order to try usual "winners" more often, increase RGB allocation size.
