[Mne_analysis] Saccade rejection by HEOG voltage

[Phillip Alday]

You could set your channel types such that only HEOG is EOG and VEOG is
misc before the rejection/epoch/average step and then change it back
afterwards if necessary.

Note that this is peak-to-peak and not absolute voltage.

Below is the definitions file I'm using, but would like to change the 'eogReject' argument to one that specifies the HEOG channel and ignores the VEOG channel. Any advice would be greatly appreciated. Thanks.
