Refactor project structure and update configurations

- Deleted the empty `__init__.py` file to clean up the project structure.
- Renamed the project from "laborious" to "ingestor" in `pyproject.toml`, updating the description accordingly.
- Improved type hints and conditional checks in the `Ingestor`, `DataManager`, `IngestorManager`, and `OpcManager` classes for better code clarity and type safety.
- Enhanced error handling and assertions in various methods to ensure robustness.
- Updated unit tests to reflect changes in class names and error handling improvements.
