[racket-dev] added function to srfi-19....

I think it's a bad idea to extend the SRFI modules with new functions.

Would it make sense to move functionality from SRFI-19 into
`racket/date' and then add the new functions there (and maybe change
the SRFI-19 implementation to re-export part of `racket/date')?
