Update whisper.cpp

[thewh1teagle]

Can we update whisper-rs to use the latest whisper.cpp version (v1.6.0)?
The new release has some fixes such as loading the model with non utf-8 path.
You can check it out here: whisper.cpp v1.6.0.

Thanks! I hope it will be merged soon.

Just a heads-up, it seems like some CI checks failed in your PR. To potentially save time on rechecks, you might want to consider running cargo fmt and cargo clippy locally.
