* feat: chicago tribune parser
Date is parsing but failing the test because:
AssertionError: '2016-12-13T21:45:00.000Z' == '2016-12-13T13:45:00-0800'
I tried to insert a line of code for Time Zone but I’m a n00b so I
don’t think I did it right.
No image showing up in the preview.
* fix: remove timezone from date_published extractor
* test: update unit tests to assert the correct value for date_published
