docx more full format

[lskatz]

Hi, following up on #14 , is there any chance of including authors and affiliations in the docx output? This would be useful for getting track changes from people who are not used to markdown but who would give me feedback through docx. Thank you!

PS: I got a github actions working with this yaml for docx https://github.com/lskatz/Kalamari/blob/f1600cf90338ea99b27a7c9433f50ce7cefc977d/.github/workflows/draft-docx.yml and so thank you so much for having an inara container and a github actions example.
