Inputs and animations

Today I made the inputs on pico, and yesterday I added the animations module!
@wilrakov is currently making the new menu with animations and I let you know how it looks when its ready :D

What I did

• made animation functions for later (just lerping between coordinates)
• made the inputs on pico (not completly finished, no way to detect when the button was just pressed)
• fixed the inputs in raylib (added the missing buttons)

Animations are not showed in the video, I havent added them to the menu yet
