Update 0.541 new physics

• Reworked tire behavior so different tire types now affect grip, slip, braking,** heat**, and load response more clearly.
• fixed a bug caused by roll over protection that makes steering not possible
• made the drag tires do wheelies again but reduced grip at high speeds to reduce rollovers when going to corners
• changed load game save slot logic. i will add a way to delete saves later
• added better loading screen
• fixed issue makes certain part of the UI unclickable
• Added more bindable controls
• Added a book to the game shows the engine parts etc. You can open it with V
• Improved gamepad right-stick camera look while driving.
• Made dyno screen can unstrap cars
• Retuned drivetrain feel, shifting, rev limiter behavior, and LSD values on some vehicles.
• You can put cars to manual now with Ctrl + R and shift with shift/ctrl.
• Added high-speed steering smoothing to make fast driving less twitchy.

i need a lot of feedback on how the cars drive. let me know if you have any feedback or any issues with certain setups
