v0.3.0

• Added support for save_table(..., mode="overwrite") to StatementExecutionBackend (#74). In this release, we've added support for overwriting a table when saving data using the save_table method in the StatementExecutionBackend. Previously, attempting to use the overwrite mode would raise a NotImplementedError. Now, when this mode is specified, the method first truncates the table before inserting the new rows. The truncation is done using the execute method to run a TRUNCATE TABLE SQL command. Additionally, we've added a new integration test, test_overwrite, to the test_deployment.py file to verify the new overwrite mode functionality. A new option, mode="overwrite", has been added to the save_table method, allowing for the existing data in the table to be deleted and replaced with the new data being written. We've also added two new test cases, test_statement_execution_backend_save_table_overwrite_empty_table and test_mock_backend_overwrite, to verify the new functionality. It's important to note that the method signature has been updated to include a default value for the mode parameter, setting it to append by default. This change does not affect the functionality and only provides a more convenient default behavior for users of the method.
