QG Notebook broken

[dopplershift]

The QG notebook was completely busted by metpy 1.0rc1. Not sure if it's a simple update, or if there's something not-so-good in the rc. (heads up @jthielen )

I'll have to take a closer look once Unidata/MetPy#1304 / Unidata/MetPy#1325 are in, but my initial guess from a quick read through is that that notebook assumes mpcalc.smooth_n_point outputs pint Quantities when supplied xarray.DataArray, which changed to outputting xarray.DataArray with Unidata/MetPy#1223.

That makes sense, I can run with that and see what happens. This is the first time I've tried to use the RC in a workshop, and I did that because some combination of xarray and pint updates broke something in getting the longitude coords.

Fixed in 455ffa0.
