@ChemiKyle, this PR is getting lonely. It is very sad.

So is @emilyolsen246 , 'cause she needs it. :-(

I was holding off on merging this because it has the strange issue in vignettes of complaining about dependencies despite them being called with library.

❯ checking for unstated dependencies in vignettes ... NOTE
  '::' or ':::' imports not declared from:
    ‘dotenv’ ‘here’
  'library' or 'require' calls not declared from:
    ‘kableExtra’ ‘tidyverse’

I'll just merge since it's blocking now and I'm not pedantic enough to consider a warning in a vignette that important.

@ChemiKyle, you were right to be concerned. The vignette would not build in Github CI. I am already working on #142.
