[BotW] update contrasty, mainly add more tonemaps

Also move credits to rules.txt, they're too much

Game original tone mapping is fine (also I can't understand it xD), but it partially causes what ppl might say "washed out".
So added another two for toggling, one is simplified ACES Filmic, which over-saturates also gives a 'film look', another is from kiri, who ripped the one in SweetFX into Clarity pack.
