Apply simple photometric model

Description
This program applies a basic photometric normalization to an image by dividing each pixel by the cosine of the incidence angle. It uses the camera
model to compute the incidence angle at each pixel in the cube. The corresponding input pixel value is then divided by the cosine of the incidence angle. If the
absolute value of the incidence angle is 90 or greater then a Null pixel will be output.
