separate individual distill posts out into separate research compendia

[maxheld83]

seems a bit dicey to run the whole thing off the same compute env -- as there are more articles, this will probably blow up at some point.
Might be nice to think of the distill posts as a release of / view into some separate repo research compendium, rather than these posts living inside the parent distill blog.

it seems like as in subugoe/scholcomm_analytics#5 what we (and many other researchers) really like about distill (and blogdown, to some extent) is, essentially, the CSS and the PR process for submitting.
But that doesn't mean the whole thing has to live inside the blog repo.

I'd have to think about how to do this, might be too complicated/thorny.
