ZIP metadata is modified when copying APK signatures
We finally have an App underway which supports shipping multiple reproducible APKs with signatures form us and the original dev1.
This feature currently only supports v1 signatures. So while both published APKs are perfectly valid signed they are quite different when you compare them with diffoscope2
So I'd like to propose to having all our sub-commands which produce or modify APKs to reformat them so that they are always using unix zip format with all files ordered strictly alphanumerically. Maybe it would be convenient to also add a new subcommand for reformatting APKs.
This would be a great first step towards supporting v2 and v3 APK signatures
