Atokaconn

Fixed
- tests responses are mocked and do not have request attributes, so its existance is checked
to avoid tests failures

- empty results in get_response_from_ids returned as a dict, not a list

- typer-cli added to dev-dependencies (helps generating docs)
- atokaconn.cli package contains source code for the cli

- allower_roles added as attribute to AtokaConn class
