Emulate keystrokes with hand poses to play Tetris.

The game of Tetris is there: https://tetris.com/play-tetris/

The hand poses used to play are:
- FIVE (open hand) to move left or right the falling piece.
The direction of the move is given by the rotation of the hand.
- ONE to rotate the piece.
- FIST (closed hand) to accelarate the fall.

Good luck !
