Pull request overview
This PR adds delta loss functionality to the auto-round quantization scheme system, making it the default AutoScheme method.
Changes:
- Introduces a new delta loss-based auto scheme implementation with gradient computation and dynamic programming optimization
- Updates the auto_scheme module to import and register the delta loss method as the default
- Implements three wrapper classes for different quantization scenarios (standard, GGUF-K, GGUF-K with imatrix)
