[issue43547] support ZIP files with zeroed out fields (e.g. for reproducible builds)

Hi,

thanks for looking into reproducible builds. I have a few suggestions:

- since it's a new feature, it cannot go into older releases.
- zeroed is not a self-explanatory term. I suggest to find a term that does describe the result, not the internal operation.
- I don't think you have to introduce a new argument at all. Instead you can provide a new method that creates a carefully crafted zipinfo object that results into zeroed arguments. That's how I implemented reproducible tar.bz2 files.
- For full reproducible builds you may have to write files to zipfiles in a well-defined order.
