mappings/VegCSV-VegBIEN.specimens.csv: catalogNumber: Moved direct/indirect voucher _ifs inwards to wrap just the value of catalognumber_dwc, not the catalognumber_dwc field node, so that a future SQL function implementation of _if only needs to concern itself with returning one value or another, not with handling XML subtrees. The previous moving of the _ifs in r3942 was intended to effect this, but the _ifs weren't moved in far enough to wrap just the value.
