We where also in contact with Peter Charlton from the University of Cambridge about this topic. He is also looking for people who write a Python Respiratory Rate Estimation Toolbox. We are physiologists, and not Biomedical Engineers specialising in signal processing for wearables as Peter is. We miss Biomedical Engineers who write a Respiratory Rate Estimation Toolbox for Python. But you have to find your own grant for doing it.
