Fix Image::ColorToGray()
...
Previous implementation had images brighter than usual. The algorithm
used was probably not necessary as it was for converting from
linear-space to a different one.

Impl output to video, update program args
...
Turns out output to video suffers from loss of quality problems when in
color (not grayscale). It may be better in some cases to just output
each frame as a png and combining them later with ffmpeg like how it is
mentioned here: https://trac.ffmpeg.org/wiki/Slideshow . Grayscale video
is noticably better, but both cases result in large video sizes, so care
may be needed if free disk-space is sparse.

Refactoring of opencl_handle and image for reuse

Refactoring was done so that the OpenCL kernels wouldn't need to be
recompiled every time an image was dithered, among other efficiency
