I think the main problem is that we currently do not have a way of saving an `IntervalIndex`, which `groupby_bins` produces, to a netCDF file:
```
In [7]: out.indexes['data_bins']
Out[7]:
IntervalIndex([(0, 2], (2, 4], (4, 6], (6, 8]],
              closed='right',
              dtype='interval[int64]')
```
One way to work around this in the meantime is to redefine the bins coordinate before saving things to a file.  See @jhamman's answer to a [related StackOverflow question](https://stackoverflow.com/questions/54848671/using-xarray-groupby-bins-results-in-coordinates-that-are-an-object-and-cant-be) for an example.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,424538928
