talk-llama : fix for swedish umlauts + expose model inference settings in talk-llama.cpp (#3187)

Quick fix for not removing swedish umlauts.

* Update talk-llama.cpp

Expose model inference settings to user instead of hard coding them. Same defaults as previous defaults.

* Update examples/talk-llama/talk-llama.cpp
