Overview

The ZipCommand class supports zipping the Excel file contents using a binary zip program instead of RubyZip's Zip::OutputStream.

The methods provided here mimic Zip::OutputStream so that ZipCommand can be used as a drop-in replacement. Note that method signatures are not identical to Zip::OutputStream, they are only sufficiently close so that ZipCommand and Zip::OutputStream can be interchangeably used within caxlsx.
