Adding a watcher directory?

When using the zola serve, I get the message

$ zola serve
...

Listening for changes in /some/path/{config.toml,content,sass,static,templates}

Is it possible to add to to the list of files/directories being watched? I’m using load_data to bring in data from another directory that isn’t in the list, so auto-reload doesn’t happen when altering those files. It would be super useful to have an command line argument to specify additional files.

Am I missing something?

It’s not possible to watch other folders

Would you be open to a PR that allows it via a command line switch?
