Postprocessor: do we need killed count

[Charlotte-Morgan]

maybe we need this for earthquake analysis?

We have now a fatality count in the EQ on population function.
Do we need it only in this hazard ?

[Charlotte-Morgan]

for now yes - but with the work @samnawi is doing and that he showed in his work on population repoorting for contingency plans; there are fatality estimates for other hazards too

As with the displacement rate, I think we should take the same implementation path and assign fatality rates per hazard class / threshold. I would suggest to default them to 0 and have a note indicating that the fatality rate is not defined. See similar notes in this vein for displacement here: #3664 (comment)
