[Imagery Plugin] Enhancements - Compass, HUD, Freshness (#3675)

* Adds a compass rose component showing spacecraft and camera pointing direction in images, as well as sun location.
* Adds a "heads up display" component that shows heading at the top of images, as well as sun direction
* Adds freshness indicators for spacecraft and camera position
