Update llama.cpp textgen settings
* Add min_keep, a llama.cpp-exclusive setting for constraining the effect of truncation samplers * Enable nsigma for llama.cpp, and add llama.cpp alias top_n_sigma, add nsigma to the llama.cpp sampler order block * Allow a negative value of nsigma as this represents 'disabled' in llama.cpp (while 0 is deterministic) * Remove tfs and top_a as these are not supported by llama.cpp (tfs was removed, and top_a was never supported) * Correct the identification string for typical_p in the llama.cpp sampler order block * Add penalties to the llama.cpp sampler order block
