Display the score

[azihassan]

The code keeps track of the player's score but it never displays it, The 8x8 screen is too small to display a double digit score, but maybe it would be possible to display one digit at a time in the form of a scrolling animation, would that be too much for the MCU ? Ideally I would also like to save the high score and display it along with the current score in the MENU state and of course, update it if the player beats it.
