Change output format

// First design - use file like as an input in sctk, resolved_packages for metadata

packages: // list of metadata like python-inspector
resolved_dependencies_graph: // resolution

    -   path: requirements.txt
        type: file
        package_data:
            -   type: pypi

// Second Design - no file sections

resolved_packages: // list of metadata like python-inspector
resolved_dependencies_graph: // resolution
primary_packages:
    -   type: pypi
        dependencies: [] // requirements in python-inspector

@TG1999 Thank you for laying out these two options. I am clearly for option 1 so we have a consistent output format with SCTK.
