Screen always on for inappbrowser (option)

I have an app that displays a realtime monitoring page using inappbrowser. Because of its realtime character it's essential that the device screen/lcd stays on while displaying the page.

Using cordova-plugin-insomnia perfectly prevents the screen from switching off when the app is active, but it has no effect on the inappbrowser-window.

It would be nice to have a inappbrowser option to set this.

Start by tracing the plugin's native Android and iOS InAppBrowser entry points and how options are handled. Compare the requested behavior with cordova-plugin-insomnia, then verify the screen remains on only while the InAppBrowser page is active and that the new option is documented for both platforms.
