Add docx template

[nuest]

We can write a function that generates (or fills in a template) a DOCX report to be filled out by codecheckers. We can try to make the coverpage look very similar to the one coming out of the Rmd template.

Note to self: This is where I created docx in R before using the awesome officer package: https://gitlab.com/nuest/forumcs-2019-osf-proceedings/-/blob/master/proceedings.Rmd#L231

great idea. We can also have a .tex format.
