Add API versioning
Add API versioning as used by Photo/Card APIs. This is required to be under /api/
as frontend path matches root. Added not to project/urls.py
about moving this if creating an API only webapp.
As a side effect of testing this also resolves #40 (closed) (actually getting this working took longer!)
Also, updates django from 2.2 to 3.1
