utils: raspberrypi: ctt: Added CAC support to the CTT

Browse source 
Added the ability to tune the chromatic aberration correction
within the ctt. There are options for cac_only or to tune as part
of a larger tuning process. CTT will now recognise any files that
begin with "cac" as being chromatic aberration tuning files.
