fix: reaction bounds in _add_cycle_free function are assigned according to the description in CycleFreeFlux paper
In _add_cycle_free function, when the original flux is > 0, the ub is forced to be the maximum value between the flux and the reaction ub. It should be the minimum between these 2 values according to the CycleFreeFlux paper. The same happens with the lb of reactions with flux < 0. It has been modified to be the maximum between the original flux and the reaction lb.
