make yaml a extra dependency

[RonnyPfannschmidt]

i'd love to use the core package, but i don't want the yaml dependency and i don't use the script

Same here. We are thinking about moving to watchdog from pure inotify in Nikola and Doit but the YAML dependency is hard to take.

I’d love to send a pull request, but I can’t get buildout to work. Here’s my patch for this feature instead:

The extra also needs to be added to script entrypoints

Nearly four years later, and a dependency on watchdog is causing all of my projects to get GitHub security audit alerts for a dependency on a library that's not even used by consumers of the library. Any chance this could get looked at again?

Thanks!

Of course, will open a PR for discussion.
