is_scalar(chunks) might be the appropriate condition. is_scalar is already imported from .utils in dataset.py

This seems to work fine in a lot of cases, except automatic chunking isn't implemented for object dtypes at the moment, so it fails if you pass a cftime coordinate, for example.

Can we catch this error and re-raise specifying "automatic chunking fails for object arrays. These include cftime DataArrays" or something like that?
