Feature request: Unattended upgrade using command line options

@Belim, first of all I want to thank you for this great tool! :)

I have one question: is there a possibility to add to FlyBy11 the option to make an [unattended](https://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/update-windows-settings-and-scripts-create-your-own-answer-file-sxs?view=windows-11) in-place upgrade using command line options where we can specify the ISO file and unattended response file (if the unattended file is not provided, use the built-in on FlyBy11)?
I was thinking something like the [MediaCreation.bat](https://github.com/jdggraaf/11_24H2-MediaCreationTool.bat) tool, where it creates an XML file for unattended installation. Maybe you can "borrow" the file from the tool (I share it here as text file, as I can't upload XML files) or build a generic one [here](https://schneegans.de/windows/unattend-generator/). The problem with the MediaCreationTool.bat is that it needs to download the ISO every time we use the tool, so the computer needs internet access to run an in-place upgrade.

Thanks again for your time and great tool! :)
