Refile and capture to result of a query

I'm not sure if this is in the scope of this project so I'm opening this issue to ask about that.

I have written a first implementation for refiling and capturing to the result of an org-ql query. This is useful for people who want more precise refiling or capturing. You can find the implementation here: https://github.com/Zetagon/literate-dotfiles/blob/master/config.org#refiling .

The code is probably not pull request ready, but if you'd like I can prepare a pull request. Otherwise I'll just leave it here in case somebody in the future looks for this functionality.
