feature request: spectrum interpolation to reduce power line noise complementary with notch filter

[XiaoyuZeng]

Hi all.

I used to analyze iEEG data using fieldtrip, and now I'm a huge fan of RAVE. I found that fieldtrip provided a novel and powerful method named spectrum interpolation to reduce power line noise. I wondered whether it is possible to integrate this method into RAVE.

Link to the paper introducing this method: Reducing power line noise in EEG and MEG data via spectrum interpolation
