EMD function for detrending

[Gr1Lo]

Hi, everyone! I really appreciate the dplR package and actively use it in my work, thank you for it. Also, I have some ideas about enlarging functional and I will be very happy if you find them useful. Participating in this project would be an honor for me.

Here I am proposing a function for performing detrending by dividing the original time series on a deterministic component, that was retrieved from empirical mode decomposition

For correct work following packages needs to be installed:

pip install -U EMD-signal
pip install -U scikit-learn
pip install -U sktime
