Update `add_bounds` to support 2D coordinate variables.

Should we change the name of this function? Some relevant existing code is here: https://github.com/NCAR/pop-tools/blob/d771f8d7280696c890bb6a21255c5ad298c8b373/pop_tools/grid.py#L324-L363 cc @huard

Add more conventions to coordinate_criteria

From @kthyng in #315 The following looks like some older convention. We could easily support this in https://github.com/xarray-contrib/cf-xarray/blob/7e663671a138d2822f696c266b3c2c7c738c7998/cf_xarray/criteria.py#L15 ``` "_CoordinateTransformType": "Vertical", "_CoordinateAxisType": "GeoZ", "_CoordinateZisPositive": "down", "_CoordinateAxes": "sigma", ```

add pretty formatting for units

Continuing from https://github.com/xarray-contrib/cf-xarray/pull/284#issuecomment-1018130308 (cc @keewis) I see pint has a "pretty" formatting mode. Is there a way we can define the "pretty" string? ```python u = units.Unit("degrees_east") f"{u:~P}" ``` ```...
