Add support for pyautogui

[link89]

Hi, do you have a plan to add pyautogui as a DC backend? It provides more operation than autopy does.

Hi there! This is a good idea so we will definitely look into it. If you really need the backend as soon as possible it should hopefully be easy enough to define a new DC class with some minimal functionality for your own use cases that we could then later extend on as well.

I have created a PR #21 addressing this that will be in draft state over the weekend but should be complete in the following weeks.

Hi @link89, the PyAutoGUI backend is now available, let me know if you have any feedback from using it later on.
