FR: use_roxytest()

[ColinFay]

Given that all project need to have the following entry in the DESCRIPTION :

Roxygen: list(roclets = c("namespace", "rd", "roxytest::testthat_roclet"))

That would be great to have a roxytest::use_roxytest() function to append that without having to look for the exact syntax :)

Happy to try a PR at some point in time

That function could also run usethis::use_testthat() if verify_testthat_used () is FALSE

@ColinFay Thanks for reporting. A PR would be much welcome!
