Currently maximization problem aren't presolved by Papilo. This PR updates obj coefficients and resets the sense when building op_problem from papilo problem. Conversions of obj coefficients are needed to validate post solve checks. The conversion in problem_t constructor is kept for the case presolve is disabled.
