fix: use globalVariables for state.abb/state.name, regenerate docs

@importFrom does not work for base R lazy data objects — replaced with
utils::globalVariables() in the package file to suppress the R CMD check
NOTE. Removed the invalid @importFrom datasets tag from utils.R.

Also commits all man/ and NAMESPACE changes from devtools::document().
