OpenXML: Option to extract XLSX by column rather than by row

[Chase Tingley]

The XLSX worksheet format is row-oriented, and so we extract it in row order: everything from row 1 is extracted, then everything from row 2, etc.

There are situations where users may want to extract by column first, for contextual reasons. This is sort of annoying to do on a parsing level, but is possible. (It is also probably a precondition to handling bilingual/multilingual XLSX, which is a more common request.)

I’ve managed to order the row/column tag name to column using PHP by parsing the resname attribute of the extracted XLIFF file.
I will be planning to implement this to Okapi soon
