Const Array Qualifier for Assets

Big thanks for @untoxa for pointing out that I should be using const on sprite and background arrays.

Collision Checking Performance Updates

Release 0.1.0 saw slowdown of gameplay when the CPU input prediction loop also checked for collisions.

• Improved collision checking to not make as many variable allocations
• Added skip_collision_checking flag during CPU input calculation

Hitbox Bug Fix

Bugfixes from feedback from the initial release:

• Car hitboxes and ball collision detection was completely re-written
• Should no longer see issues with the ball passing through the car.
