Fix enabling "tweaks" crashing the game without YACL installed
Port to 1.20.3
Port to NeoForge. Compatibility with transparent crosshair through Auto HUD.
Add option to make modifiers replace the main crosshair.
Slightly improve the crosshair mixin. This fixes the debug crosshair hiding, as well as a compatibility problem with Shoulder Surfing Mod + Do A Barrel Roll.
