Low Priority: Removal of view_as_windows from CUCIM if redundant

[Eve-ning]

currently in glcm_cupy/glcm/glcm.py, we have

from cucim.skimage.util.shape import \
    view_as_windows as view_as_windows_cucim

from glcm_cupy.utils import view_as_windows_cp

...

if USE_CUCIM:
    ij = view_as_windows_cucim(
        im_chn, (self._diameter, self._diameter)
    )
else:
    ij = view_as_windows_cp(im_chn, (self._diameter, self._diameter))

which may be redundant, if view_as_windows_cucim does not perform any essential speedup over view_as_windows_cp.

• view_as_windows_cp is an adaptation of skimage.utils.view_as_windows, with cp.ndarray substituting np.ndarray

This is not essential to fix, low priority.
