Showing shared locations in a WearOS map tile

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

The Google Maps app on WearOS doesn't show people that share their location with you. Home Assistant to the rescue (I hope)!

**Describe the solution you'd like**

I would like a WearOS tile that shows a map of persons that have shared their location with me. I'm thinking this could be done by using device trackers from HA. Ideally with the possibility to zoom and pan the map.

**Describe alternatives you've considered, if any**

I don't think any exists.
