message: indexcodec: Fix an off-by-one error in the bounds check
  The check was a bit too aggressive - it's valid to have a mesh that has
  no aux/varint bytes (in fact all meshes built out of disjoint triangles
  or quads get there with codeaux table encoding), so the condition should
  be strict.
