Please release 1.9.4 to fix lxml constraint

Hi there! #183 relaxed this package's `lxml` version constraint, but since that change hasn't yet been included in a release, `htmldate` is still causing dependency resolution conflicts for its consuming packages (e.g., `ddgs`, `trafilatura`). To prevent downstream consumers from having to include older, possible-insecure package versions, could we release 1.9.4?
