Ortools-sirius and MPS problems about antares_simulator

[jmkerloch]

When using OR-Tools, MPS are written with OR-Tools object MPSolver::Write method.

This method use SiriusInterface::Write method :

void SiriusInterface::Write(const std::string& filename) {
		if (sync_status_ == MUST_RELOAD) {
			Reset();
		}
		ExtractModel();
		VLOG(1) << "Writing Sirius MPS \"" << filename << "\".";
		const int status = SRSwritempsprob(mLp->problem_mps, filename.c_str());
		if (status) {
			LOG(WARNING) << "Failed to write MPS.";
		}
	}

This should work but the method SRSwritempsprob does nothing in sirius :

int SRSwritempsprob(PROBLEME_MPS * problem_mps, const char * fileName) {
	PROBLEME_A_RESOUDRE problem_a_resoudre;
	PROBLEME_PNE problem_pne;
	PNE_copy_problem(problem_mps, &problem_a_resoudre, 0, 0.0);
	//FIXME PNE_EcrireJeuDeDonneesMPS_avecNom(&problem_pne, &problem_a_resoudre, fileName);

	return 0;
}

This issue is still valid. Move the MPS writing function from Antares to Sirius Solver.

@klorel can we offer a fix for this in Sirius ?
