I think dask array has some utility functions for "unifying chunks" that we might be able to use inside our map_blocks() function.

Potentially we could also make Dataset.chunks more robust, e.g., have it return None for dimensions with inconsistent chunk sizes rather than raising an error.

Alternatively, we could enforce matching chunksizes on all dask arrays inside a Dataset, as part of xarray's model of a Dataset as a collection of aligned arrays. But this seems unnecessarily limiting, and I am reluctant to add extra complexity to xarray's data model.
