Adjust RNNoise for different Sample Rate

[radito]

The current implementation of RNNoise is fixed to 48000 Khz sample rate and not properly tested in AudioThread, the implementation is not that correct because the buffer is fixed to rnnoise buffer which is 480 items and need to work on that

To Do List:

• Test behaviour RNNoise on different sample rate
• Adjust buffer size to match the original if possible
• Add resampling when sample rate changes
