Include a copy of
cupyx.scipy.ndimage.find_objectsthat was contributed upstream.A couple of cuCIM functions that used
find_objectsare also updated to use this implementation instead of copying to host to call the SciPy version.See: cupy/cupy#8916
The version vendored here is modified to exclude the Cython-based slice list comparison as we don't support using Cython code from cuCIM. This version will still provide good acceleration and we preferentially import the version from CuPy instead if it is available.
