Missing Marker Column in Output (Muse2 with BlueMuse) about eeg-expy

[ErikBjare]

Thinking about this again, I think I may be the one to blame. Regression probably happened in my "continuous recording to file" PR to muse-lsl: alexandrebarachant/muse-lsl#139

Maybe we should open an issue there instead? Or just figure out how to fix it (shouldn't be too hard) and submit a PR straight away.

I am a complete novice as far as EEG-Notebooks or the topic of streaming goes. Just wanted to say, that I had the same issue (#111) in both cases: when I used BlueMuse for streaming and when I used Petal Metrics. Petal Metrics gives the option to choose either LSL or OSC as the stream type. I previously used LSL, but just now tried out the OSC option, however the problem persists - at the beginning the event markers are not recorded - the first one that gets recorded is always on data row 13 (row 14 in the file).

In order to do some further testing, I also experimented with Visual N170, Visual SSVEP and Auditory Oddball (orig) - in all the cases the title of the "Marker" column was missing from the experimental data file, as well as the first 12 event markers. Hence, the issue is not specific to the Visual P300 experiment.
