This node allows to setup the Panorama:

1/ Enables the initialization the cameras from known position in an XML file (provided by
["Roundshot VR Drive"](https://www.roundshot.com/xml_1/internet/fr/application/d394/d395/f396.cfm) ).

2/ Enables to setup Full Fisheye Optics (to use an Equirectangular camera model).

3/ To automatically detects the Fisheye Circle (radius + center) in input images or manually adjust it.
