Add suport to django > 3.0 and drf > 3.9

I was using the base_name argument on the urls of my app but i believe drf isn’t supporting it anymore because when testing the following error is returned.

Traceback (most recent call last):

I see that you merged #186 which should add support for Django 3 but didn’t create a new version for pypi.

Lately I am thinking in just deprecate DRF 3.11 in December. Holidays will (hopefully) let me take care of this.

You are right. This is cumbersome and letting people confused.
