Calculate Epileptogenicity Index for EEG/iEEG

[zhengliuer]

Hi, in epilepsy, Epileptogenicity Index(EI) in this paper is as important as HFOs.

I noticed that calculation of EI hasn't been implemented in Python, only in MATLAB-based software AnyWave, the code of which is close-source.

I've been trying to implement this method recently, and I think this could be a function of mne-feature.

If so, what API is appropriate? Like compute_EI?

Thank you @BarryLiu97 for your interest in mne-features.
This would be a good feature function for mne-features!
Feel free to start a PR and implement a compute_epileptogenicity_index function.

OK, great!. I'll open a PR when I finish the implementation locally.
