Some updates to the tuning for the imx296 sensors.
For the colour variant:
* Minor change to the AWB curve, making things a little less green.
* Updated CCMs that reduce colour saturation to a more accurate level.
Thanks to Dr. Rolf Henkel for these measurements and calculations.
* Sharpening has been toned down quite a lot.
* rpi.focus algorithm added so that the focus measure can be accessed.
The sharpening and focus changes are applied to the mono version of
the sensor too as we expect similar characteristics.

The sensor black level is 60 (in 10-bits), fix this in the mono variant tuning
file.

Append "_mono" to the sensor name when generating the tuning filename for
monochrome sensor variants. So the new naming convention is as follows:
<sensor_name>.json - Standard colour sensor variant
<sensor_name>_mono.json - Monochrome sensor variant
Rename the existing imx296.json file to imx296_mono.json as this tuning file
is based on the monochrome variant of the IMX296.
