About iEEG Reader #13605
Description
Describe the problem
Currently, mne bids is not reading .mefd/ for the IEEG dataset.
My understanding is that we should read it because it's a valid format in iEEG bids.
What's the best way to proceed in this case?
I saw some datasets on OpenNeuro with this format; I counted 13 datasets.
Describe your solution
Implement some way to read this.
Describe possible alternatives
Create a way to perform a conversion in real time, instead of reading.

Looks like it might be supported by neo https://neo.readthedocs.io/en/0.4.1/io.html#neo.io.MicromedIO
So maybe in MNE-Python we could add a lightweight reader that wraps
neolike we do forneuralynx
