Haven't defined zip file

[Julian-O]

The specification doesn't specify what a Zip file is.

At the least, there should be a link to either the 2015 ISO standard or alternatively Pkware's technical note (including a version number).

Is there a GZip variant?
Similarly, are there 7Zup, bzip2, and rzip variants?
Is Zip64 supported, to allow more than 4GB files?

Great suggestions. I’ll add this in a day or so unless you provide a PR first 🤪
