Updated setup.py

Changes include:
- Removed support for versions of setuptools prior to 18.0 (dating to early 2015)
    - This removed some extra logic related to conditional dependencies and simplified the imports
- Added a python_requires statement to require Python 3.4 or newer
    - I believe this requires setuptools >= 34.4
