Change White Matter removal process for electrode plotting

[Aaronearlerichardson]

Change the electrode parcellation label picking process from current implementation to match the MATLAB implementation.

[Aaronearlerichardson]

Current intended MATLAB implementation: coganlab/MATLAB-env#7

Current label picking logic implemented here:

IEEG_Pipelines/ieeg/viz/mri.py
