Feature Request: ability to check camera altitude.

Currently WebODM allows us to be able to look at individual camera positions and see the image captured by that particular shot. I think it would be useful if we can also check the altitude of the camera from the ground to better understand the behavioral Characteristics of the software when the height is varied.

This feature will really be useful for folks who want to have a deep understanding of aerial mapping for academic purposes.
