[BUG] Unzipped files have no permission on Linux

Describe the bug When unzipping a ZIP file created with client-zip (non-service worker version), the resulting zipped files have no permissions in Linux and are therefore locked. Once you change the permissions, the files work as expected.

I tried using a File object and an object literal to represent each file and had the same outcome.

To Reproduce Steps to reproduce the behavior:

1. In a Linux environment, create a ZIP file using client-zip
2. Extract the files
3. Extracted files should have no permissions and possibly display a locked icon over them

Expected behavior I expect the extracted files to have 664 permissions on Linux. This works as expected on Mac and Windows.

Thanks for your feedback. I’ll publish the fix as soon as I have a moment of free time.

Thanks for digging. If I understand correctly, it’s not even an extra field, just a few bytes in the basic file header that I thought were not important and was leaving at zero.
