Move several imports to the top-level of the file This better follows PEP 8 style guide: https://www.python.org/dev/peps/pep-0008/#imports > Imports are always put at the top of the file, just after any module > comments and docstrings, and before module globals and constants. This also avoids duplicate import code within the same file.

py3k: Import Christoph Gohlke's test suite This is Christoph Gohlke's test suite from his personal PIL package found at http://www.lfd.uci.edu/~gohlke/pythonlibs/. This is just to bring it in as a separate commit. Future commits will align it with Pillow.

Introduce isort to automate import ordering and formatting Similar to the recent adoption of Black. isort is a Python utility to sort imports alphabetically and automatically separate into sections. By using isort, contributors can quickly and automatically conform to the projects style without thinking. Just let the tool do it. Uses the configuration recommended by the Black to avoid conflicts of style. Rewrite TestImageQt.test_deprecated to no rely on import order.
