reduced the need for autoexposure, by increasing ambient light with low sun, which mimics the dynamic range of the eye quite well. as a result autoexposure range reduced so it should be impossible to notice now but will make small adjustment if there is a significant change in brightness. leave a comment if you find a track/car/time combo that the exposure/autoexposure transitions are still an issue on.
note: this inevitably won't look as good for screenshots during evening/morning, as overall contrast will probably be lower, but obviously that wasnt the goal of this mod
adjusted fog which got left out of previous update.
