Describe the new feature

The HiGHS (highspy in particular) API doesn't currently load the duals / reduced costs / slacks / shadow prices into pulp from highs, but they are present in highs (admittedly, the slacks aren't quite present, only the row values, but slacks can be computed easily from those).

I do have a commit ready to go for this, a PR will be raised in a few minutes referencing this.
