GBIF downloads: iterate on verbatim records

[niconoe]

It's currently easy to go from the ibterpreted occurrence to the verbatim one, using the extension mechanism.

should we provide something to iterate on verbatim occurrences (ideally with a way to retrieve the interpreted record)?

Yes, I think this would be immensely useful.

Great to know you're interested, John!

I can foresee a rather simple way to achieve the first part (iterate on verbatim rows instead of interpreted ones as the Core data file), but the second part (allowing to go from a verbatim record to its interpreted counterpart) may be more problematic, especially performance-wise).

My question is therefore: do you think the first part is "good enough" at first?
