Request: Examples of basic zip/unzip functionality using Node.

[ipmcc]

It occurs to me as I try to use JSZip in a Node.js-based CLI tool that an example of the basic functionality I expect/enjoy from the macOS-provided zip and unzip on the command line would be really helpful. Not even esoteric functionality like passwords or updating or anything like that, but just like "take a bunch of files and folders and produce a ZIP file" and "take a ZIP file and produce a bunch of files and folders." Thanks!
