package/iana-assignments: new package

The fixing of [1] and related code reviews [2] and [3] highlighted the
need for a package providing a versioned PEN (Enterprise Numbers)
registry file from IANA (Internet Assigned Numbers Authority).
The GitHub repository from which this package originates is a mirror of
the IANA registries periodically updated from https://www.iana.org/protocols.
