Hysteria shader & basic sunburn config & 1st person fire tweaks

Changed Hysteria shader default params

- slightly less desaturation but not complete removal
- caves now have true darkness (shaders override minecraft gamma, however true darkness will be retained as a fallback)
- basic sun burn config that allows players to retreat to other dimensions (with a sun) to avoid getting burned
- fire resist potions prevent sun burn from even applying (prevents the fire effect from showing on the screen as a result)
- tinted glass prevents sunburn
- added vanilla tweaks lowered first person fire
   this was added because although the create netherite diving gear stops fire damage, the player still renders as on fire in both 3rd and 1st person blocking half the players view.
