Radiation improvements

[Oct0bass]

Feature I think mek's radiation system is currently a bit lacking, and could use some improvements. Some of these have been mentioned before:

• Harmful status effects. Before you start taking damage you should receive some harmful effects, such as slowness, nausea, blindness, hunger etc. The effects and level would depend on the radiation, obviously. No directly damaging effects (poison, wither etc) because radiation already does that.
• More damage with higher radiation levels. Was really surprised to find out this wasn't a thing, when I accidentally created over a petasievert in my creative world, and the mobs still took a good few seconds to die. That much radiation should kill them instantly, pretty sure.
• More random radiation. Radiation IRL isn't constant, you measure "mean lethal dose" and such. Radiation should be a bit random, but not much, maybe the max amount of time to die from a certain amount of radiation is about twice the minimum?
• Environmental effects. Has been suggested before, so not going to say much about it, but they would be nice. Alternatives Mek's current radiation doesn't really feel like radiation, just "mysterious force that kills players".

We are not doing nausea, as for slowness and blindness personally I am against it but no idea, and radiation already affects your hunger, at least indirectly. The reason we don't just apply a ton of potion effects is that: a. In my opinion that is just the lazy way out for implementing things and we wanted our system to be more unique b. There are tons of things in Minecraft especially modded that allows for removing various potion effects.

In regards to higher damage, I agree that it would make sense to have it scale upwards and probably will look into this for 10.1

Radiation is already relatively "random": https://github.com/mekanism/Mekanism/blob/1.16.x/src/main/java/mekanism/common/lib/radiation/RadiationManager.java#L212-L214 https://github.com/mekanism/Mekanism/blob/1.16.x/src/main/java/mekanism/common/lib/radiation/capability/DefaultRadiationEntity.java#L50-L56
