Fast flex: Interpolate contact points directly.
...
For each contact point, we used to first compute the vertex weights on a triangle and then add a contact point per vertex using the flex interpolation (trilinear or quadratic), obtaining the total weight by multiplying the vertex weight and the basis function value at that vertex. After this change, each contact point is added directly by evaluating the basis function directly a the point.

Create mjpDecoder, mj_parse, and mju_decodeResource
...
- plugin system similar to mjpResourceProvider, but instead of loading a resource it converts an existing mjResource into an mjSpec.
- The returned spec is then composed into the referencing spec.
- This enables different file types to generate arbitrary specs, and allows us to separate format parsing from compilation code.
Follow up CLs will move some of the logic in src/engine for PNG, USD, KTX, OBJ loading into decoders.
The mj_parse function MjSpec from a given file, it's a more generic version of mj_parseXML.
In it's implementation, mj_parse as opposed to mj_parseXML will look for any registered decoder and
not assume we are striclty dealing with MJCF.

This ensures that at e.g. the barycenter of the triangle each vertex has weight 1/3, as one would expect with barycentric coordinates, rather than 1/sqrt(3). This makes it consistent to the finite element interpolation used in the passive elastic forces.
