Someone asked if we could support this: https://pandas.pydata.org/pandas-docs/stable/user_guide/window.html#window-exponentially-weighted

I haven't looked at it much, but it seems like this should be possible with some cumulative expression kung fu.

Exponential smoothing only looks at the previous value. I think it's just using a .diff() might do.
