fix for #291. The root issue is that the set of antecedents is recycled as a fixed object between routines. Antecedents that were already allocated for a Gomory cut got reset by the internalizer. This causes unsound bounds axioms to be created

refine the safety check for leaving basis. As long as all base variables are unbounded in compatible directions as the non-basic variable we can detect unbounded variables. This partial check fixes integer divergence in a case exposed by Karpenov. Establishing or converting this to a check that always identifies unbounded integer variables is left for further analysis.
