3.2.2

This release is mostly a large refactor of how the documentation is organized, managed, and produced. There are also significant new sections about the CoffeeGrinder and CoffeeFilter APIs.

Other aspects of the build have also been improved: the Maven artifacts now explicitly identify either Saxon 11 or Saxon 12 as dependencies; build automation now tests against both versions of Saxon, and the default build dependency is Saxon-HE.

No significant changes; dependencies updated to the latest version.
