> pandas has the concept of a [Grouper|https://pandas.pydata.org/docs/reference/api/pandas.Grouper.html], which can be passed to groupby to provide additional metadata. Currently we don't support these in the DataFrame API, we assume all arguments are just labels.
> We should explicitly reject these for now, then add support for them.
