[localization] Partially calibrated Camera RIG localization in an existing reconstruction

[simogasp]

Resectioning from externally calibrated camera RIG: 2 calibrated cameras + 1 camera with unknown intrinsics (the 3 are externally calibrated, though):

• this is useful for the main camera (shooting camera) as it may change the focal length during the shooting while the witness are supposed to stay fixed)
• [ ] RIG camera pose estimation using the N calibrated cameras
• for each uncalibrated camera
  • use normal localization (voctree+matching)
  • use 3D points and pose of the main camera (which is known from the extrinsics) ==> this in case of large occlusions on the main camera preventing the use of voctree
  • BA to refine intrinsics of the main camera

depends on poparteu/openMVG#13
