This should use the `__getitem__` logic and return `None` if `__getitem__` files so that the two are consistent (as expected from dicts and other mappings)

Continuing from https://github.com/xarray-contrib/cf-xarray/issues/124#issuecomment-765725229 Creating "minimal" examples is going to be slightly annoying since we will mostly care about `.attrs` and `.encoding`. Maybe we should have a bug report template that...

wrap facetgrid objects

This will allow `fg.cf.map_dataarray(x="longitude", ...)` Adding `xr.plot.FacetGrid` to `_WRAPPED_CLASSES` and some tests should be enough (?)

climatological statistics / ClimatologyIndex?

http://cfconventions.org/Data/cf-conventions/cf-conventions-1.8/cf-conventions.html#climatological-statistics This seems like a useful feature to have under the `ds.cf.clim` namespace at least for simple reductions like `cf.clim(time="D").mean()`.
