#163 Allow newer versions of lxml.

In 5c23f6f lxml was bumped from 3.6.1 to 3.6.4 to fix #108. At the time we were cautious to increase it any further since unit tests and integration tests hadn't been passing for roughly one year.

With unit tests and continous integration in place again, I think we can open up lxml to allow more recent version. This would likely fix the user's issue reported in #163.
