This commit adds support to using Xiph and Mozilla RNNoise library for noise reduction. RNNoise is a small library using an AI approach to noise reduction using a pre-trained model like RTX Voice. But unlike RTX Voice, it is very tiny, use CPU instead of GPU and only use little resources. Obviously it is not as efficient but will effectively remove background noise. It uses more CPU than the existing libspeex-based noise reduction but it also sounds sounds way better. RNNoise support is added to the noise reduction effect. It can be enabled with a checkbox in the effect configuration. RNNoise has no settings.
