Inputs for estimate_generalized_absolute_pose

[Alex-Beh]

Hi, thanks for open source this great library.

First question, does estimate_generalized_absolute_pose equivalent to the Non-central absolute pose in OpenGV?

Understand that the result, CameraPose, is the transformation from world coordinates to camera coordinates. However, in the case of multiple cameras, to which camera does it refer? Another question arises regarding the input camera_ext: does it also follow the same convention, representing the transformation from world coordinates to the respective camera?"

I am trying the library but encountering some weird results; there is definitely something wrong with my setup. I will continue debugging, and if I cannot resolve the issue, I will share the code here.
