// I just pasted this together from things found scattered around the internet. Primarily: https://github.com/Emperorlou/MidJourneyTools
//
// To enable periodic downloading of newly-created images, go to a 'recent creations' page, and add "&autosavetimer=60" to the URL;
// something like: `https://www.bing.com/images/create/-/1234?autosavetimer=60`.
//
// This implementation is designed to be left unattended - periodically reloading itself. If you click a link it will disable the script,
// unless you remove `?*autosavetimer=*` from `@match` above.
