Title: Fix: Handle .zip Files When Generating Python Packages

Description:

This Pull Request addresses an issue where fpm fails to properly generate a package when the Python module is downloaded in .zip format via pip. Previously, fpm expected only .tar.gz archives and would throw an error when encountering a .zip file due to an unexpected directory layout.

Changes made:

• Added logic to detect if the downloaded Python package is in .zip format.
• Implemented functionality to properly extract .zip files using the unzip command and handle the packaging process as usual.
• Maintained backward compatibility for .tar.gz files.

Testing:

• Verified the fix by packaging Python modules provided in both .zip and .tar.gz formats.
• Both archive types now process correctly, and the expected packages are generated without errors.

This PR resolves issue #2072, where users encountered a runtime error when pip fetched .zip files during the fpm packaging process.
