      Given a tuple containing bounding box coordinates, return a tuple of slice
      objects.
  
      A bounding box in the form of a straight list is returned by several
      functions in skimage, but these cannot be used to direct index into an
      image.  This function returns a tuples of slices can be, such as:
      ``im[bbox_to_slices([xmin, ymin, xmax, ymax])]``.
  
      Parameters
      ----------
      bbox : tuple of ints
          The bounding box indices in the form (``xmin``, ``ymin``, ``zmin``,
          ``xmax``, ``ymax``, ``zmax``).  For a 2D image, simply omit the
          ``zmin`` and ``zmax`` entries.
  
      Returns
      -------
      slices : tuple
          A tuple of slice objects that can be used to directly index into a
          larger image.
