Byte alignment of resulting zip archive

[hybridherbst]

Some formats (e.g. USDZ, which is a uncompressed zip) have specific byte alignment constraints, namely that files start at 64-byte boundaries. (see USDZ docs)

I'm able to generate ZIP files using jszip just fine, but I can't find a way to enforce these boundaries. Is there one? If not, please consider this a feature request :)

Edit: guess that would go here?
