Hi @toncho11, thank you for the suggestion!

What do you think about making a contribution to add this dataset? Here's a tutorial on how to do it: http://moabb.neurotechx.com/docs/auto_tutorials/tutorial_4_adding_a_dataset.html#sphx-glr-auto-tutorials-tutorial-4-adding-a-dataset-py

I think it can be a nice contribution to the open-source community :)

I can support you in PR.
