        Scenario:
        In this example which demonstrates the problem... We have two dictionaries containing lists for
        individualNames.  Each list contains exactly 2 elements. The effective change is that we are
        replacing the 2nd element in the list.
        NOTE: This is considered a REPLACEMENT of the second element and not an UPDATE of the element
        because we are providing a custom compare_func which will determine matching elements based on
        the value of the nameIdentifier field.  If the custom compare_func is not used, then
        deepdiff.diff will mistakenly treat the difference as being individual field updates for every
        field in the second element of the list.

        Intent:
        Use our custom compare_func, since we have provided it.
        We need to fall into self._precalculate_distance_by_custom_compare_func
        To do this, we are proposing a change to deepdiff.diff line 1128:

        Original:
            if hashes_added and hashes_removed and self.iterable_compare_func and len(hashes_added) > 1 and len(hashes_removed) > 1:

        Proposed/Updated:
            if hashes_added and hashes_removed \
            and self.iterable_compare_func \
            and len(hashes_added) > 0 and len(hashes_removed) > 0:

        NOTE: It is worth mentioning that deepdiff.diff line 1121, might also benefit by changing the length conditions
        to evaluate for > 0 (rather than > 1).
