low level examples broken after [feat: Update sampling API for llama.cpp (#1742)]

[mite51]

I believe that after the commit for "Update sampling API for llama.cpp (#1742)" the low level examples broke.

Traceback (most recent call last):

The class LlamaSamplingContext is still there, but no longer used, in fact it cannot be used because sample_repetition_penalties was removed. Also, a request, an example of how to get sorted candidate data after a sample would be appreciated, I had a fork using LlamaSamplingContext to store and return candidate data, but that no longer seems to be possible, or at least its no longer clear to me how I might do something similar.
