Adding code and bitmap for the PyBadge Blinka Jump game Learn Guide.
Expected behavior:
-Press start to begin playing after powering up
-Blinka has a slither animation
-If you press A, Blinka jumps. Jump to clear the Sparky sprites
-3 Sparky sprites are randomly generated to scroll across the screen
-Crash detection is in place if Blinka and a Sparky collide
-Hearts at the top of the screen reflect game lives. If Blinka collides with a Sparky then you lose a life
-Score at the top of the screen is a count of time.monotonic() with 10 points added every time a Sparky is jumped over
-Once all 3 lives are spent, "Game Over" text is displayed in the middle of the screen. You can press start to start a new game
