fix canvas randomly flipping (fixes #24)

    const pixels: string[] = [];

    for (let x = 0; x < this.CANVAS_SIZE[0]; x++) {

    // (y -> x) because of how the conversion needs to be done later

    // if this is inverted, the map will flip when rebuilding the cache (5 minute expiry)

    // fixes #24

    for (let y = 0; y < this.CANVAS_SIZE[1]; y++) {

      for (let x = 0; x < this.CANVAS_SIZE[0]; x++) {

        pixels.push(

          (await redis.get(Redis.key("pixelColor", x, y))) || "transparent"

        );

      data: { lastPixelTime: new Date() },

    });

    await redis.set(`CANVAS:PIXELS[${x},${y}]:COLOR`, hex);

    await redis.set(Redis.key("pixelColor", x, y), hex);

    // maybe only update specific element?

    // i don't think it needs to be awaited
