sim_fibo_ad: completely replace the old eclipse parser by the new one

this required to abandon the "Epoch" stuff which the new parser does
not have (as well as the ECLIPSE file format knows nothing about
epochs). Handling well controls properly thus has to wait until Joakim
and Kristian finish refurbishing the WellsManager, so as a stop-gap
measure, only the first "epoch" is run.
BlackoilPropsAdFromDeck: Add support for PVTO
sim_fibo_ad: add macro to easily switch between the old and the new parser
