ale.util.generate_kernels_from_cube does not load a user-specified DSK path of a cube

[ryodohemmi]

After running ISIS8.3.0's spiceinit with shape and model options, applying ale.util.generate_kernels_from_cube to the output cube gives a list of kernel paths other than the DSK's full path.

>>> test_cub = "h5851_0000_nd3.cub"
>>> kernels = ale.util.generate_kernels_from_cube(test_cub, expand=True)
>>> print(ale.util.write_metakernel_from_kernel_list(kernels))
