Django 3.0 Not Supported

[gopackgo90]

I'm not sure if there are any other issues, but Django 3.0 removed support for django.utils.six which django-braces uses in a couple of places. Django recommends either removing the dependency on six altogether or depending on six directly. Similarly, django.utils.functional.curry() was removed, which needs to be replaced by either functools.partial() or functools.partialmethod().
