What's Changed

• preliminary support for log_probs using the compute_log_probs=True model constructor arg.
• A new guidance.cpp module that allows us to have high speed implementations of key objects.
• reduce memory requirements (and probably improve speed) for llama.cpp tests by @paulbkoch in #485
• Many bug fixes :)
