[Eeglablist] Get Clean Raw Data to report removed channels

[Clement Lee]

Hi Paul,

Here's a line I just wrote that hopefully helps:

rmChanIdx = find(~ismember({EEG.chanlocs.labels},
{cleanedEEG.chanlocs.labels}));

IIRC CRD changes the chanlocs structure when removing channels. If this is
the case, we can compare the chanlocs structure before and after clean raw
data. `rmChanIdx` stands for removed channel indices. You can access the
channel labels with `EEG.chanlocs(rmChanIdx).labels` to see the labels of
the removed channels.

Best,
