Failures with newer Sphinx

[tylerjereddy]

Using the version of Sphinx that requirements/doc.txt pulls in for the main SciPy repo will fail to build this project with i.e., make dist per the output/error below. A simple workaround is to use an older (6.x series) version of Sphinx for now.

sphinx-build -b html -d build/doctrees   . build/html
