Docx writer tests: Use new golden framework

These are based off the reader tests, with some removed (where the
reader output was identical, based on different docx inputs). There
are still more to be added. In particular, tests for custom-styles
need to be added.

All golden docx files have been checked in MS Word
2013 (windows). There is no corruption.

There is questionable output in the `tables` test: the three tables
seemed to be joined. This will be addressed in a future commit, and
the golden docx file will be changed.
