Performing a representative sphinx-build (10 x docutils/docs/ref/rst/restructuredtext.txt, dummy builder), and analysing with py-spy, you can see from the attached flamegraph that the smartquote transform accouts for over 22% of the build time!

This PR attempts to improve that situation (at least down to 18%) by caching regex compilation
