message: indexcodec: Update static codeaux table
  Since we can't use 0xf elements anymore, regenerate this table using the
  training mesh set as a reference; the elements are taken using
  normalized probabilities from meshes with >100 triangles that use codeaux.
  This reduces the resulting size by up to 1%.
