Using `ispyb.open` causes ispyb.model deprecation warning

[ndevenish]

ispyb.open imports:

ispyb-api/src/ispyb/__init__.py

Line 51 in 8c952b5

from ispyb.connector.mysqlsp.main import ISPyBMySQLSPConnector as Connector

This imports ispyb.interface.connection:

ispyb-api/src/ispyb/connector/mysqlsp/main.py

Line 12 in 8c952b5

import ispyb.interface.connection

and this imports ispyb.model:

ispyb-api/src/ispyb/interface/connection.py

Line 4 in 8c952b5

import ispyb.model.interface

Thus, you cannot use ispyb.open without getting the warning:

ispyb-api/src/ispyb/model/__init__.py

Lines 3 to 8 in 8c952b5

	warnings.warn(
	"ispyb.model has been deprecated and will be removed in a future version. "
	"You can use the SQLAlchemy models in ispyb.sqlalchemy instead",
	DeprecationWarning,
	stacklevel=2,
	)

Are all non-sqlalchemy connection deprecated, or just ispyb.model? (AFAIK the sqlalchemy credentials don't have stored procedure access or insertion/update permissions, to get the same results - the credentials I am aware of can only see the update_session_archived procedure)
