Adds new function in MeshManager for performing convex decomposition

[iche033]

🎉 New feature

replaces #583

Summary

Adds function for doing convex decomposition using the header only library V-HACD.

The new function take a submesh and returns a vector of decomposed submeshes. Currently a couple of parameters are exposed:

• _maxConvexHulls: max number of convex hulls to produce
  • value: 16 (default in V-HACD: 64)
• _voxelResolution: resolution of voxels to use when decomposing the submesh
  • value: 200000 (default in V-HACD: 400000)

These default values for these parameters are lower than the default values provided in V-HACD for a faster convex decomposition process as the process with original values could take quite some time for complex meshes.
