fips_info should not sort and remove duplicates

[aavogt]

I was surprised that fips_info would sort and remove duplicates from the argument.

Current:

fips_info(c("21","20","20"))

  abbr fips     full
1   KS   20   Kansas
2   KY   21 Kentucky

Expected:

  abbr fips     full
1   KY   21 Kentucky
2   KS   20   Kansas
3   KS   20   Kansas

In other words

 new_fips_info <- function(fips) if (length(fips)!=0)
     merge(list(fips=fips), fips_info(), all.x=TRUE )

This comes up when I want the state name from the fips stored in df$fips. I expected this to work within(df, state <- fips_info(fips)$full). Instead merge(df, fips_info(), all.x=T) %>% rename(state='full') will do.

That's a good point, I'll look into making that change.
