Fixes jungleland mobs dying to toxic water + deep toxic not being stronger

[Moltijoe]

I just copied from old code, apparently it never checked for WEATHER_ACID immunity but it also never checked anything other than a human so they were immune, not because of their immunity, but because they weren't even being looked at in the first place

this also meant that if a human got acid weather immunity, they'd still be affected anyway

also, i removed an unintentional part of deep toxic water being significantly more dangerous

Testing
