Add Support for llama.cpp Models

[Talnz007]

I’d like to suggest adding support for llama.cpp models to expand Alpaca’s compatibility, especially for users with older AMD GPUs that can leverage Vulkan for GPU-accelerated inference.

This would allow users with older GPUs to take advantage of Vulkan for GPU-accelerated inference, ensuring smoother performance and opening up Alpaca to a wider range of hardware setups.

Thank you.
