No Sieges in Fallout/Harsh Heat or Cold

[CortexVortex08]

If a band of enemies start to siege you in hard fallout or a very harsh winter or summer, they tend to start dropping dead and you can easily wait them out. So, I suggest that raiders no longer siege while there is a setting deadly enough to kill them, so they do not die of radiation sickness, hypothermia, or heatstroke.

In order to fix this, you could add in a "Siege has been called off." response if one of these weather effects happens while they are besieging your colony, and the enemies feel that they can no longer hold out in the conditions presented to them, and have no sieges start in conditions they cannot survive in.
