Updated IOU and accuracy calculations to handle division by zero. Currently, a RuntimeWarning is thrown when performing the category-wise IOU calculation, if the total_area_union or total_area_label for one of the categories is zero. This can be handled by using the np.divide function, simply returning 0 for all categories where this happens.
