A full Musculoskeletal model

[adakri]

Hello,

Thanks for the great work! I was wondering if there was any plans of releasing a full musco-skeletal model (or if that already exists and I have just missed it). There was a reference of this in {"Differentiable Biomechanics Unlocks Opportunities for Markerless Motion Capture", R. James Cotton} and was wondering if there is a special branch or a wip version of that already implemented in myosuite.

Thanks again for the great library.
