Provide a demo mode to walk through the process

Is your feature request related to a problem? Please describe.

• As a first time user I found the software a bit daunting: you have no good idea what steps are involved and how OpenAndroidInstaller will handle it.
• It helps to know what is coming to make the right decision. I only found out about the options to add 'addons' like MicroG in the flashing screen. I didn't know that at the step to select an image and was already looking online for a LineageOS with MicroG image. Looking ahead in demo-mode would have made me aware of the option to add addons.
• I want to demonstrate how easy the software is to intested persons. A demo-mode would allow me to walk that person through the process almost like a presentation, without the delays or dependency of an actual phone to flash.

Describe the solution you'd like
Some button at the beginning screen to start a demo mode. All UI steps will be followed for a particular model (just choose one by the developers) without actually doing something.
A more interesting feature might be to read the phone status if possible and then continue the demo for that specific device instead of a generic one.

Describe alternatives you've considered

• Video: already on the website, typically not available offline, not easy to click through on your pace and video would have to be updated for each version,
• More documentation. Would be nice but is hard to get as compelling as just clicking through the process.
• Regarding the addons knowledge, this could be mentioned in the page for choosing the image: "Later you'll have te options to expand LineageOS with addons like microG."

Additional context
Used in context with inexperienced flashers interested in giving OpenAndroidInstaller a try.

That's a great idea!
This should be relatively easy to add to a certain extend.
I will look into it!
