WIP: Fix pycodestyle errors (#653)

* Fix pycodestyle errors

W503 is condracting PEP-8 and was added to the default ignore list by
pycodestyle developers

* Use setup.cfg for pycodestyle ignore parameters

Addresses #651 (kind of). Appending ignores to the default list prevents
us from getting warnings that we don't care about.

* W503 is not in the default ignore list in 2.4.0
