[RFE] Add interactive mode

[lapo-luchini]

It was implemented in llama.cpp already, we can probably take much inspiration from there.

Seems interesting! Which PR are you refering to exactly in llama.cpp?

I did notice the "--interactive" parameters in the util.cpp (while searching for diffs that could make it work on Windows), but seems to be originated here:
ggml-org/llama.cpp#61

That's a really nice feature!
Let me know if you want to work on it, or I can try to add once I've got a chance 🙌
