[FR] Run from Login Window

Describe the solution you'd like
SwiftDialog v2.5.0 and above support running from the loginwindow. I would like erase-install to be able to display its progress windows from the login window - in our case we have a large number of lab devices (no filevault) and when we are upgrading macOS (erase > upgrade OS > software deployment) during hours of operation we would like our support staff to know this workflow is taking place without having to login to the device, while at the same time be able to spot any that are stuck or failing to progress.

This would require deployment of a LaunchAgent with something similar to below:

<plist version="1.0"> <dict> <key>OnDemand</key> <false/> <key>LaunchOnlyOnce</key> <true/> <key>ProgramArguments</key> <array> <string>/Library/Management/erase-install/erase-install.sh {$params}</string> </array> <key>LimitLoadToSessionType</key> <string>LoginWindow</string> <key>Label</key> <string>com.erase-install-login-window</string> </dict> </plist>

Describe alternatives you've considered
I have tried using outset with limited success - at the time this worked but only after you logged out of an active user session. During a cold boot it would not display the workflow but the launch agent would work as expected and erase install would run in the background. Simply modifying the super script to add --loginwindow to each of the defaults was enough. However much more testing would be required if the solution was to be 100% reliable. There was a found enhancement available for swift dialog to improve the detection of this loginwindow process but I have still been unable to achieve it.
