What's Changed
* Fixed type declaration for `service_account_json_file`. This caused the program to crash when this parameter was specified
* Improved performance through refactor of methods `convert_types_and_add_metadata -renamed-to-> convert_types` and `_yield_rows_from_file`. The new version extracts some computation outside of the for loop.
* Dropped support for python 3.13
* Shortened the schema definition json files: Removed unnecessary & ignored details.
