Feature: location report viewing

[AGaylord6]

Helper function that takes a list of LocationReport objects (or json's) and creates a simple map that shows the locations reported. It could open a window or just create and store a html file.

This could give users a quick and easy way to see where their device is after fetching its reports without having to look up latitude/longitude.

Hmm, this would be interesting. I don't really intend on FindMy.py to become a 'do it all' project and would rather stick to it being a library only, but at the same time this seems simple enough to implement and would be quite nice to have. A proper CLI is on the roadmap for the (distant?) future, this would probably be good to have as a CLI feature.
