This change introduces `nflexstiffness` and `flex_stiffnessadr` to allow flex stiffness matrices to have sizes other than the fixed 21 per element. Higher-order flexes can now store larger stiffness matrices based on their number of nodes. The `flex_stiffnessadr` array provides the starting index for each flex's stiffness data within the `flex_stiffness` array.

Unity Plug-in
The MuJoCo Unity plug-in allows the Unity Editor and runtime to use the MuJoCo physics engine. Users can import MJCF files and edit the models in the Editor. The plug-in relies on Unity for most aspects -- assets, game logic, simulation time -- but uses MuJoCo to determine how objects move, giving the designer access to MuJoCo's full API. See documentation and installation instructions here.
