Add support for OpenAi Whisper Model

[bezaleel22]

I appreciate your work on this, can support for OpenAi Whisper Model be added. I'm new to rust and cxx, I can create a PR so you review and correct if you don't mind.

I want to use this library for a project but I need the whisper bindings

Sorry for my late reply. Since I’ve been busy recently, I might be unable to add support for Whisper Models, but any PRs are welcome.

I'm also looking for using whisper with ctranslate2 in Rust.
It should work 2/3x times faster than whisper.cpp
Does the bindings ready or need to write them?
That's why I asked about integration bindgen so we can easily access whole ctranslate2 functions
