Add "Flat ZIP" preset to sub context menu in Windows

[piyushjaiswal2bytes]

Feature Request

Add a new context menu option in Windows Explorer's right-click submenu for 7-Zip called "Add a Flat ZIP".

Behavior:

• When selected, this option should:
  • Open the selected folder
  • Select all contents (equivalent to Ctrl + A)
  • Invoke 7-Zip > Add to archive
  • Set the following automatically:
    • Format: ZIP
    • Compression: Store (0)
    • Archive Name: Use the name of the selected folder (e.g., FolderName.zip)
• The process and resulting archive should be exactly as if these manual steps were performed in sequence.

Motivation:

• Streamlines the workflow for quickly creating non-compressed ZIP archives from a folder.
• Saves time and reduces manual steps.

References:

• Similar behavior as manual selection and context menu -> 7-Zip -> Add to archive.
• Requested for enhanced user convenience.
