The astatus value was being interpreted as FZ, F2 and F1 causing bizarre
readings and all other channels to be shifted one place.
Additionally the datasheet has been updated to re-order F5, F7 and F8 to
F7, F8, F5, so these channels have been re-ordered accordingly.
Note: This will turn sensor output from confusing abject nonsense into
what looks like pretty reasonable colour data and fixes#989.
