[Open-transport] Hafas Raw Data Format to GTFS conversion (Zürich)

I'm pretty busy this week, but i can look into it.
I've build multiple  GTFS converters for multiple formats, this format
looks somewhat similar to IFF but seems to be binary?. OpenPlanB worked on
converting data from the HAFAS CD's but never completed a GTFS converter.

In any case the startpoint is to dump the data into tables and then build a
series of SQL query's to convert it to GTFS schema.

Kind regards,
Thomas Koch
