AF3: Change logic for energy deposits outside of calorimeters

In physics validation we saw that there are spikes topocluster distribution in AF3. This is a result of energy building up in the edge cells of calorimeters that get assigned all the energy beyond the calorimeter boundary. This MR changes the logic to scale up the energy within the calorimeter rather than re-assigning the energy in cells outside the calorimeter.
