Before this change, MjDataWrapper contained a custom data structure called MjDataMetadata, which contained the sizes of various arrays needed to create MjData. This was used for serialization and deserialization, as well as copying MjData instances.
This worked fine for native MuJoCo models, but as soon as plugins were used, there was information in the model that was needed and not available in MjDataMetadata. Since plugins are so general, keeping MjDataMetadata was untenable.

The viewer currently hard crashes when the user script loops on the passive viewer handle without paying attention to `is_running`. This is considered user error, however this change makes the user script hang on the loop rather than hard crashing.

Renamed `mjModel.eq_active` to `mjModel.eq_active0`, which now has the semantic of "initial value of `mjData.eq_active`".
Fixes#876.

By more carefully inverting the operations performed when OpenGL
transforms metric distance to window coordinates, more accurate
depth values can be estimated from the depth buffer
Combined, both options greatly improve camera depth accuracy compared to
OpenGL default Z mapping and int24 depth buffer.
Requires GL_ARB_clip_control and ARB_depth_buffer_float extensions
Although the path doesn't exist on disk, dlopen seems to be previously redirecting to the correct file, but this stopped working in macOS 14.

- See public description below.
- Stopped incrementing the iteration count in saveStats().
- `sizeof(mjSolverStat) == 40`, so this ends up costing 160KB, up from 40KB.
BEGIN_PUBLIC
Changed the size of `mjData.solver`, the structure used to collect solver diagnostic information. The array is now of length `mjNISLAND * mjNSOLVER`, where each row of length `mjNSOLVER` contains separate solver statistics for each constraint island. Until solver islanding is implemented, only row 0 is used.
- The new constant `mjNISLAND` is set to 20.
- `mjNSOLVER` is reduced from 1000 to 200.
- Added `mjData.solver_nisland`, the number of islands for which the solver ran.
- `mjData.solver_niter` (renamed from mjData.solver_iter) and `mjData.solver_nnz` are now integer vectors of length `mjNISLAND`.

Add missing `ctrl` attribute to keyframe indexer.
END_PUBLIC
Context: Making an LQR notebook for the Skydio drone and wanted to read the ctrl attribute in the keyframe stored in the XML.
