AutoScenarioDbTable - NotImplementedError for DB reflection

[victorterpstra]

The statement table = Table(self.db_table_name, metadata_obj, autoload_with=engine), as used for the AutoScenarioDbTable, throws a NotImplementedError.
The AutoScenarioDbTable uses this to get the Table and Columns from DB reflection. Instead of the regular ScenarioDbTable, in which the user codes the Table in Python.

In Windows, a revert to SQLAlchemy <1.4 seemed to work.
But not in CPD 4.0.5

This relates to difficulty in upgrading to SQLAlchemy 1.4

(In the issue, someone recently posted a work-around)

Addition problem is that Pandas 1.4 requires SQLAlchemy 1.4, so we will need to upgrade soon
