This commit adds support for saving and restoring cumulative production quantities like WOPTH, GWPTH, FGPTH, GGITH, and WWITH. While here, also cater to the case of wells alternating between injecting gas and injecting water. This means that we'll save and restore cumulative gas/water injection for all injectors, irrespective of current injecting phase. Update unit tests accordingly.
