Add debugging logs and update dependencies for compatibility

- Added detailed print statements throughout the code to assist in debugging and monitoring the execution flow.
- Logs include information about starting main functions, downloading models, initializing components, preprocessing images, and reconstructing 3D models.
- Ensured each major step, including input validation, model loading, and GPU allocation, has informative logging.

- Updated `requirements.txt` to resolve compatibility issues:
- Downgraded `numpy` to `<2.0` to address incompatibility errors with PyTorch.
- Added `pybind11>=2.12` to support compatibility between NumPy 1.x and 2.x.
- Pinned `torch==2.1.2` to ensure compatibility with Hugging Face ZeroGPU Spaces.

These changes will help ensure the code runs smoothly with the updated versions, and the added logs will facilitate easier debugging and error tracing.
