Initial separation of tabyl

[billdenney]

Fix #240

This PR should import all functions from tabyl before being committed. That will require tabyl being on CRAN.

Nicely done! So first order of business is, get tabyl onto CRAN? They are slower with new package reviews than they are with updates.

We are past due to fix #582 which was closed in #584. I wonder if I should just branch off the repo at 2.2.0 and cherry that one fix in, then submit to CRAN as 2.2.1. That should get a very fast review and maybe beat the holiday rush?

[billdenney]

Yeah, the first order of business is to get tabyl onto CRAN. I agree that this may be better after the janitor update, but if we are lucky, they may review tabyl quickly... Maybe?

I think that we nearly have tabyl to a good state to be a separate package. Maybe try to push it when everything is cleaned up there and see if it (surprisingly) goes quickly?

@sfirke, If some of the author(s) of janitor were solely focused on tabyl and not other janitor functions, they should probably be removed with this merge (because they will be in the tabyl list). Can you please review that?

Before we re-import the tabyl functions and after tabyl is on CRAN, I will test reverse dependencies and notify packages that depend on janitor to switch to tabyl.

I think that this means we will not get this PR into janitor before the required CRAN update. (Let's give ourselves breathing room.)
