Added A2B test code

Added a mode to iccdump that generates test data for A2B.
For now, I was constructing it via CMD scripting, but we
should automate this further (python?), and perhaps use
the same method for other parts of the profile testing).

Currently:
> CD profiles && DEL a2b.h
> FOR /R %F IN (*.icc) DO ..\out\msvs\iccdump.exe -t %F >> a2b.h
