Add readr local edition downgrade

[katy-sadowski]

Workaround for a bug in vroom (tidyverse/vroom#519) which is causing test failures in R CMD Check on MacOS, and may also cause errors for users in certain circumstances (the bug is still not well understood). The solution follows what was done in a Bioconductor package here, and this seems like a legit fix, as the 1st edition of readr is still supported and the main change between editions seems to be the switch to use vroom. The csvs we're reading in DQD are small so I don't have performance concerns.
