By using both serial and parallel coarsen methods from ``dask``, we are adding a dependency but we are ensuring forward compatibility. @shoyer, what's your preference? (1) replicate serial coarsen into ``xarray`` or (2) point to ``dask`` coarsen methods?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,198742089

1. If the underlying data to ``x`` is ``dask.array``, yields x.chunks(chunks).array.coarsen(reduction, axes, trim_excess)
2. Else, copy the ``block_reduce`` function.

Does that fit with the ``xarray`` API?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,198742089
