Introduces two new nodes for generating UUIDs:
- `UUIDGeneratorNode`: Generates a standard UUID4.
- `EnhancedUUIDGeneratorNode`: Provides options for generating UUIDs of types 1, 3, 4, and 5, with configurable namespaces, names, prefixes, and suffixes.
This commit also includes necessary updates to `pyproject.toml` and `__init__.py` files to integrate these nodes into the ComfyUI environment.
