Dask LocalClient breaks spacy models.

[rtbs-dev]

It appears that having a running dask client scheduler means that the individual workers cannot get called (get_workers() returns None), and trying to load a spacy/scispacy model installed in the activated environment means the workers cannot access the model. Running the non-client dask routines seems to work fine, if slower.

This seems in contrast with the "closed" issue/workaround here: explosion/spaCy#5111

The Code here is built around trying to use that workaround for a decorator factory, to allow arbitrary functions. Not currently working (may have to wait for spacy v3?).
