Async task that updates PIL Image with Game of Life
"""
Game of Life async task that updates passed PIL Image with generations
loosely based on https://codereview.stackexchange.com/questions/125292/conways-game-of-life-in-python-saving-to-an-image
but fixes the critical bug which runs the frame update loop on a transient grid resulting in wrong behaviour - I don't have enough points to post fix!
Copied from part of a bigger project I'm working on, this can still be run with the python flipdot module imported using a script.
