Overwrite the intrinsic parameters of cameras in an SfMData scene with a pre-calibrated intrinsic.

This node replaces the intrinsics of all (or selected) cameras in the input SfMData with
the intrinsics from a calibration file. The calibration file can be either an SfMData file
or a dedicated lens calibration file. This is useful when a precise factory or lab calibration
is available and should be enforced instead of the intrinsics estimated during reconstruction.
