Replace deprecated pygame.image.fromstring with pygame.image.frombytes

[JaskRendix]

The function pygame.image.fromstring has been deprecated since Pygame version 2.3.0. As per the official documentation, pygame.image.frombytes should be used instead. This update ensures compatibility with newer versions of Pygame while maintaining the intended functionality.

Great catch. Is that also compatible with old pygame versions such as 1.9.6 or 1.9.3? As we also support these
Maybe adding

version_major, version_minor, _ = pygame_version
if version_major > 2 or version_major == 2 and version_minor >= 3: your code, else, original?

added if / else against vernum

I didnt know that I could do that >= (2, 3, 0)
Thanks. Merging.
