 * Scenarized & hourly values for hydro pumping and hydro generation. Previously this data was not scenarized and daily.
 * STS groups are now "dynamic" : group names are no longer fixed by code, user is free to define these groups.
 * Add optimization options from command line in OR-Tools / XPRESS (#1837)
