Add Python TSFEL library support for feature extraction

[perellonieto]

The TSFEL: Time Series Feature Extraction Library for Python was released recently. This library may incorporate very useful feature extraction methods that we do not have currently.

Is it possible to incorporate the library into some of our feature extraction functions? Maybe as a wrapper to TSFEL, or as examples on how this can be done.
