Do something about README.Rmd --> README.md

[jennybc]

Currently README.md can grow stale because nothing one does in the normal course of development will cause it to be re-rendered.

We've discussed that it should be probably rendered via devtools::document().

pkgdown is also relevant, but it was recently decided that it's confusing for pkgdown::build_site() to modify files outside of docs/.

Also connected to vignette development workflows, which are up in the air:

Rebuilding README.md (+ improved vignette workflow) should also involve installing development package to a temporary library.
