Rebalance food spoil

In my opinion, processed or fermented food should have much longer spoil timer. The spoiling is overall too fast in the game, for some of the foodgroups. For raw food, the current rate is ok, except for the prime meat. The processed food spoils way too fast. Some even spoils before the buff run out. For fermented food, like pickled carrot, it should last a long time before spoil. Like in RL. For long missions, you should be able to make buffed food that last long, to take with you.
