Importing hypernetx freezes while loading HIF JSON Schema

[colltoaction]

Describe the bug
Importing hypernetx freezes while loading HIF JSON Schema. I'm not sure why it freezes but in any case I think loading the schema from the internet at this point is not intended behavior.

HyperNetX/hypernetx/hif.py

Line 13 in af6c3f0

resp = requests.get(schema_url)
