Aspect Ratio Fixing

Turns out the game looks super off when displayed full screen on a not 4:3 monitor so I tried to fix it today. With the help of "Auto Letterbox" from Tom Elliott in Unity Asset Store I was able to fix it super fast. The letterbox works as intended and UI element doesn't wander to random spaces.

Meanwhile, I also found out how to export games directly to steam deck, and it looks great!
