[MRG] Adding eye tracking to ch map

[christian-oreilly]

PR Description

Very small PR just adding eye-tracking types to the channel mapping. Without this, MNE Raw objects with eye-tracking data cannot be exported to BIDS. Exporting with this change seems to fix the bug. We also had to make sure there were not NaNs in the raw objects using

def fillna(raw, fill_val=0):
    return mne.io.RawArray(np.nan_to_num(raw.get_data(), nan=fill_val), raw.info)

but I did not include this in the PR as it seems like a larger issue.

Related to #1342. Not sure if enough to close that issue.
