[argyllcms] Using the Four-Color Matrix Method in ccxxmake

Hi all,

I've been playing with the four color matrix method (by Yoshihiro Ohno
and Jonathan E. Hardis, 1997) and found that I can get a more accurate
colorimeter calibration matrix from 15 patches as I can from 832
patches and trying to find the local minimum like ccxxmake does. I
wondered If I'm missing something obvious and why the latter is used.

Thanks,

Richard.
