File permissions and OTP 27

[sgessa]

Thank you for working on this amazing library!

I am using packmatic to create a zip on the fly downloading files from AWS S3.
After unzipping the archive, I see the files have mode 000 which makes the file unreadable.

$ unzip export.zip
$ ls -l export/test.csv
---------- 1 root root 875 Jan  9 17:38 export/test.csv

I am using Elixir 1.17.3 on OTP 27.2.
I saw there were changes in OTP 27.1 in the zip module:

# HIGHLIGHTS

- The `zip` module has been updated with support for:

  - zip64 archives - Archives larger than 4GB or with more than 2^32 entries.
  - extended timestamps - Higher resolution and in UTC.
  - UID/GID - Save and extract the original UID/GID.
  - Fixes so that permission mode attributes are correctly read and set for
    files in archives.
  - zip:list_dir/2 now also returns directories, not only files. (You can
    disable this behaviour by using the option `skip_directories`).

  Various bugs in the original implementation have also been fixed, such as:

  - Correctly encode and decode the DOS timestamps for entries within an archive
    (that is the non-extended timestamp).
  - Fix DOS timestamps to be set to localtime instead of UTC (use extended
    timestamps for UTC timestamps).
  - Use the unix file attributes read from disk when creating archives instead
    of setting everything to 644.

Could you please look into this? Thx
