Lightning Optimizer v1.1.0

Updates:

Toggle Switch: Made FPS HUD toggle by F8. You can now turn the Lightning Stats overlay ON or OFF whenever you want (Highly requested by Inky_TheRobot).

Smooth Warp Animation: The HUD no longer just "pops" in. It now features a sleek Slide-in/Warp animation from the right side of the screen for a more premium feel.

Broad Version Support: Fully compatible with Minecraft 1.20.1 through 1.21.x, including the latest snapshots.

Performance Optimization: Refined the internal logic for Java 21, ensuring the optimizer boost calculation is smoother and uses even fewer resources.

Bug Fixes:

Fixed an issue where the HUD remained visible while in Cinematic Mode (F1).

Corrected the FPS calculation logic for low-end systems to provide a more stable number. 

Removed the bug that makes the fps in the HUD show negative FPS.
