As discussed in #591 it might be possible to build up the inverse of the Gauss Newton matrix directly without materializing the Gauss Newton matrix (as currently done here).

On top of a potential speedup, this could increase the precision as it avoids Sin 2 of the 7 sins of numerical linear algebra
