TelemetryDashboard: Add ROS 2 map widget

[Ryanf55]

Request

I want to view telemetry from my drone using the ROS 2 interface. This issue is for viewing the GPS position on the 2D map.

Design Ideas

• Modify the map widget to support subscribing to the /ap/navsatfix topic using roslibjs. I've used roslibjs, it's easy.
• Display the drones heading using /ap/geopose topic
