ds005 - add model used in pybids tuto?

[Remi-Gau]

that seems like a low hanging fruit that could be added, no?

Is there a sensible model in there? I recall one that is mostly meant to exercise the common functionality but wouldn't actually be interesting.

[Remi-Gau]

I guess it depends what we mean by sensible.

Do you mean something that run an actual analysis?

Guess that's not the worst model, though it does need fixing. It would be good to make sure that PyBIDS can actually construct design matrices for it. I suspect the dataset-level model would fail, unless sex is already binary...
