Errors when using rdflib 5.0.0

[gneissone]

I am receiving an error with the vivo-rdflib-sparqlstore library when using it with rdflib 5.0.0.

Traceback (most recent call last):
  File "people.py", line 20, in <module>
    from lib import backend
  File "/Users/benjamingross/Documents/git/.../toolkit/lib/backend.py", line 15, in <module>

    from rdflib.plugins.stores.sparqlstore import (
ImportError: cannot import name 'NSSPARQLWrapper'

I believe the core issue is that rdflib previously included a SPARQLWrapper dependency, but that changed with rdflib 5.0.0.

See RDFLib/rdflib#744.
rdflib 5.0.0 documentation is here: https://rdflib.readthedocs.io/en/stable/
