Map mesh indices to (quantized) MPS indices.

Given integer coordinates of a discretization Mesh, this function computes the corresponding MPS indices consistent with the linear mapping defined by mps_to_mesh_matrix. Since that forward mapping is generally non-injective, a unique inverse does not exist; the mapping back to MPS indices is therefore constructed here algorithmically by decomposing mesh indices into their quantized components.
