Reintroduce: Zoom to selected satellite

[ajmas]

Reintroduce functionality to allow zooming to focus to a selected satellite.

This is currently missing in the current implementation, but what present in the original implementation.

Should explore the original code and see if we can borrow anything from it.

The original used a camera lock function that rotated the camera every frame to match the lat/lon of the dot (calculated the lat/lon/alt from the eci coordinates in the position).

Here is one of the best implementations of camera controls around a satellite I have ever seen: https://satellitetracker.net/
