Support for mono / single channel signal

[raphaelmenges]

Hello 👋,

To my understanding, the library currently only supports stereo signals as per signature of forward :

pub fn forward(&self, input: ArrayView2<T>) -> Result<Array3<Complex<T>>, String>

Do you plan to also support audio signals with a single channel aka mono signals?

Hi, thank you for the suggestion.

Eventually yes, but I'm currently busy building out another project at the moment. This would also be lower priority compared to #3. Though, I'm happy to accept contributions.

You can also just duplicate your mono signal or leave it zeroed out along the other dimension as a workaround for now.
