Query Apple's FindMy network with Python

Everyone who shares location with me does so over Find My, and my family insists on using AirTags. As a 100% desktop Linux and mobile Android user, it is one of the few things that I always need to remote in to my Mac Mini to access because there are no x-platform FindMy apps and the FindMy iCloud web app does not have feature parity to the macOS and iOS apps. One of a long list of offenses where Apple refuses to make things easy for x-platform friend groups and families. Very annoying.

A truly x-platform app is one that works well on all 5 of these platforms, e.g. Signal. A moderately x-platform app is one that works well on the two mobile operating systems and on web as an alternative to desktop, e.g. WhatsApp. A single-platform app, like Apple FindMy, only works properly on e.g. Mac + iPhone. Apple tends to be the only major industry player that produces these sorts of apps, e.g. iMessage, FaceTime, Final Cut Pro, Keynote. Although with Keynote you can often get by with the iCloud web version, which has a useful 80%-or-so of the desktop app's features. Even apps like Meet, Zoom, and Teams -- run by rival companies -- are more x-platform than major Apple apps.
