This is quick adaptation from my py5 imported mode sketch at:
https://abav.lugaralgum.com/sketch-a-day/#sketch_2024_07_09

Use arrows to play - up to rotate, space bar to restart.

What changed: py5pjs didn't have random_choice, so I had to import it, and
in pyp5js the arrow key constants are different ARROW_LEFT and not LEFT, etc.

Beware py5 might be unable to load some SVGs... an error message will be printed.
This version will not try to scale images to fit the screen.
