- `muscle` actuators take a new `tausmooth` attribute (defaults to 0) which when positive, smooths the transition between activation and deactivation timescales.
- `mju_muscleDynamics` takes 3 parameters, adding width of smoothing sigmoid.

We are currently passing a value previously returned by setlocale to a later call to setlocale, but the spec says that we should be making a copy of it.

Going forward, the version number at head will be kept one ahead of the latest released version. The rationale behind this change is so that it is clear that the source code at head is more recent.

* Fix small bug when registering resource providers.
* Add test cases for OS filesystem fallback with VFS.
* Rewrite LoadModelFromString using a resource provider (now can pass custom VFSs).

At present, if a VFS is used but an OBJ or PNG asset doesn't exist in the VFS, the model compilation will fail without trying to first locate the asset on disk.
This breaks the Python bindings `MjModel.from_xml_string` almost entirely when OBJ assets are involved.
Also modify error messages to disambiguate between different modes of asset loading failures.

This change also requires user scripts to explicitly synchronize changes to physics state to the viewer. The Simulate class was reconfigured so that certain UI events are handled during this sync operation, outside of the render loop on the main thread. These correspond to operations that require access to the full mjModel/mjData.
To support other, more interactive operations (e.g. camera movements), a new mjvSceneState struct is introduced which captures only the portion of the physics state required for scene re-rendering. The mjvSceneState is updated from mjModel/mjData during the viewer sync operation, and is significantly cheaper than a full mj_copyModel and mj_copyData.

A resource provider provides a mechanism for MuJoCo to read from filesystems other than the OS filesystem or the Virtual File System (VFS).

Keeping this rarely-used setting complicates the compiler logic and is blocking future improvements. In order to convert older models which used this option, load and save them in MuJoCo 2.3.3 or older.

actdim has a default value of -1 (==unset), which means it currently gets saved for all actuators. After this change, it will only be saved if the value is > 1, errors are thrown for stateful actuators with actdim=0 and stateless actuators with actdim>0.

This checked that individual char arrays in the MJCF schema were not null, which would never really happen, and triggered some compiler warnings
