numpy v1.20.0 introduced type hints which leads to some mypy errors in xarray. This is the minimum set of changes to make mypy happy again. I tried to avoid #type: ignore and Any but in some instances I think it was not worth it.

I am sure there is much more fun to be had with numpy typing ;-)

Looks good! Thanks a lot for doing these @mathause

if dtype is None:
if isinstance(array, pd.PeriodIndex):
dtype = np.dtype("O")
dtype_ = np.dtype("O")
