Implement IANA model and BibXML

[ronaldtse]

Data source is available here:

https://github.com/ietf-ribose/iana-registries

e.g.
https://raw.githubusercontent.com/ietf-ribose/iana-registries/main/service-names-port-numbers/service-names-port-numbers.xml

Output in a manner like https://xml2rfc.tools.ietf.org/public/rfc/bibxml-iana/reference.IANA.service-names-port-numbers.xml

<reference anchor="SERVICE-NAMES-PORT-NUMBERS" target="http://www.iana.org/assignments/service-names-port-numbers">

@ronaldtse should we use the https://xml2rfc.tools.ietf.org/public/rfc/bibxml-iana/ as a data source?

@andrew2net No... See this: ietf-ribose/bibxml-data-iana#2
