1.2.0 - SQLAlchemyDataLayer missing required get_element() method

[hayescode]

Describe the bug
1.2.0 refactored the base data layer class and improved checking. The SQLAlchemyDataLayer is missing this abstract method and throws an error when attempting to instantiate as before.

    db = cl_data._data_layer = SQLAlchemyDataLayer(conninfo=creds['SQLALCHEMY_CONNINFO'], ssl_require=True, storage_provider=adls, user_thread_limit=100, show_logger=False)
                               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Can't instantiate abstract class SQLAlchemyDataLayer with abstract method get_element
