The color temperature member of the image object was named "col" in the
past. Now it is named "color" (which is still not very expressive).
There are still a few unspotted accesses to the col member. Fix them to
access the color member.

Tuning fails for raw images that don't have the channels ordered in
RGGB. In 19dc8c28f6 ("utils: tuning: libtuning: Implement the core of
libtuning") the channels of the image were reordered to RGGB
unconditionally in _read_image_dng(). That change was not applied to the
ctt_awb code, so that the channels were reordered twice. Fix by removing
the double ordering.

Copy ctt_{awb,ccm,colors,ransac} from the raspberrypi tuning scripts as
basis for the libcamera implementation. color.py was renamed to
ctt_colors.py to better express the origin.
The files were taken from commit 66479605ba ("utils: raspberrypi: ctt:
Improve the Macbeth Chart search reliability").
