If you group a `Dataset`, each time you apply to a `Dataset`, too.

You can certainly still use `np.convolve`, but you'll need to manually apply it to numpy arrays extracted from a Dataset and then rebuild another Dataset or DataArray.

The work around is not to provide an encoded dtype if the variable already has the dtype you want.

NumPy gives a pretty unhelpful error message. (If only we had static typing in Python...)

I have a partial fix for this in https://github.com/pydata/xarray/pull/867, but we clearly need some more tests to verify that groupby with a multi-index works properly.
