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.

Replace the Cam object with a list parameter to be able to call the
ctt_awb.awb() function from libtuning code.

To be able to use the awb function copied from the Raspberry Pi tuning
scripts in the libtuning code, we need to remove the Cam object. Use the
logging framework to replace all accesses to Cam.log.

Tuning fails for raw images that don't have the channels ordered in
RGGB. In 19dc8c28f63c ("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.

In the Image class the variable holding the color temperature is named
color instead of col which was used by the raspberry pi scripts. Rename
accordingly.

Fix imports to match new structure in the files copied from Raspberry
Pi. Add missing imports in macbeth.py. Add missing dependencies to
requirements.txt.

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 66479605baca ("utils: raspberrypi: ctt:
Improve the Macbeth Chart search reliability").
