fix: Correct advanced generator call and add auto-download to loader

- Fixes a TypeError in the advanced generator by removing the 'compiled_model' kwarg before the function call.
- Adds automatic model downloading to the HunyuanVideoFoleyModelLoader, ensuring the advanced workflow can self-initialize. This resolves issue #22.
