dask.bytes.local

I'm getting the following error trying to use this package:

```
     27 import dask.bytes.core
---> 28 from dask.bytes.local import LocalFileSystem
     29 
     30 from azureblobfs.fs import AzureBlobReadableFile, AzureBlobFileSystem

ModuleNotFoundError: No module named 'dask.bytes.local'
```

Am I missing a dependency?
