951: ufunc calls with mixed args and upcast types r=hgrecco a=keewis This fixes an issue with calling ufuncs with mixed args including upcast types: Calling a bivariate ufunc like `np.maximum(da, 0 * ureg.m)` resulted in `pint` trying to work with upcast types because `__array_ufunc__` works with type objects while `is_upcast_type` checked object instances. - [x] Executed ``black -t py36 . && isort -rc . && flake8`` with no errors - [ ] The change is fully covered by automated unit tests Co-authored-by: Keewis <keewis@posteo.de>
