pysift uses urlparse

[TimotheeWrightFicha]

Hello, Thanks for developing this library !

Trying to run it with Python 3, I faced :

File lib\site-packages\pysift\api.py:3
-> from urlparse import urljoin
ModuleNotFoundError: No module named 'urlparse'

Looking at this github answer, from urlparse import urljoin should be replaced by from urllib.parse import urljoin

No time to make a PR sorry, hope that helps still
