Critical Hours (#3849)

Co-authored-by: Conor Brady <[email protected]>
- Critical hours are calculated for each station within a fire zone unit. A representative start and end time is then selected for the fire zone unit.
- Critical hours are saved in a new critical_hours table.
- This is a temporary implementation that will be replaced once we are able to perform critical hours calculations spatially. As this is temporary there are no tests.
- A lot of functionality is borrowed/copied from FireBat.
