Support getting current detected locale of audio file

[GewoonJaap]

I think it would be nice to be able to get the current detected locale of the audio file. When using the auto detect locale function you sadly can't retrieve what the detected locale is. I see that the detected locale is being logged, so it should be available somewhere in the WinWhisper framework, but I guess it isn't exposed in C# yet :(

Afaik know, after executing whisper_full_with_state, the variable language inside the state variable is updated to the auto detected language. However in C# the state is a IntPtr and not bound to a object, I haven't researched yet how to convert this to an object..

Hello @GewoonJaap , Yes, it is possible to get the detected language, using the property: https://github.com/sandrohanea/whisper.net/blob/main/Whisper.net/WhisperProcessorEvents.cs#L73C5-L73C36 on the SegmentData.

You can only retrieve that when a segment is returned, there is not faster callback that you can register. Would that be enough for your use-case?

E.g.:

        // Creating Processor etc...
        await foreach (var result in processor.ProcessAsync(fileStream))
        {
            Console.WriteLine($"The spoken language is: {result.Language}");
            Console.WriteLine($"{result.Start}->{result.End}: {result.Text}");
        }

Oh that's really nice! Didn't know it was possible. Thank you :)
