Flux integration misses z_max layer

[Christian Herenz]

line 104 in lsd_cat_measure lib

def gen_nb_image(cube, z_min, z_max):
    return np.sum(cube[z_min:z_max,:,:],axis=0)

should be cube[z_min:z_max+1,:,:], otherwise the maximum layer is not included in the integration.

[Christian Herenz]

include z_max layer in flux integration - fixes #17
