Gamma Shifter - FullBright & Auto Night

Additions

-Added keybinds to set gamma to the maximum vanilla value (100%) and to the maximum value (1000%). Set to '[' and ']' respectively by default.

Changes

-Gamma values now snap to the nearest 50% when changed.

Fixes

-Fixed bug where gamma changes would be buffered when the mod was toggled off, and then applied when the mod was toggled back on.
-Fixed bug where toggling the mod on/off would not respect changes made to the gamma through the settings menu.
-Fixed compatibility issue with Sodium that reintroduced bugs.
