I recently learned that tqdm can automatically create a progress bar for you when you are doing expensive groupby/map operations. See for instance here: https://stackoverflow.com/questions/18603270/progress-indicator-during-pandas-operations

Would it be simple to implement something similar in Xarray? The documentation seems to read as if the groupby is heavily inspired by pandas.

Is your feature request related to a problem? Please describe. No, everything works as expected, this would just be a "quality of life" improvement.

Describe the solution you'd like

The implementation in tqdm states: Registers the given `tqdm` instance with `pandas.core.groupby.DataFrameGroupBy.progress_apply`.

I suppose something similar would need to be implemented in Xarray, and then we might be able to copy the tqdm logic.

Describe alternatives you've considered I could loop over whatever dimension I have and make my own progress bar, but that seems like defeating the purpose of groupby.
