DOC First commit for python tutorial

[remidbs]

Added a pure torch version of the train/test tutorial.

Most of the data loading and preprocessing is similar, main differences are the two last paragraph showcasing a torch training loop and an equivalent pytorch lightning loop.

Thanks for these nice edits!

Just did tiny edits, otherwise LGTM :)

I also added you as an author now that you built on this.

I'll need your workflow approval to ensure I didn't break any CI job.

Thank you so much @remidbs!

Once the CI has been updated, you can check out your tutorial on the braindecode dev page.

Congratulations on your first PR on braindecode ;) Feel invited to always contribute to braindecode!

Please let me know if there is any way to do more cross-over between what you are working on and the braindecode (maybe another biosignal). I'm super interested in having you on board!

[remidbs]

Thank you! pleasure to collaborate! looking forward to the next time :)
