ORB_SLAM3 fork bugs

[cheng-chi]

Hi Steffen, thank you so much for your work on GoPro SLAM! I'm a robotics PhD student trying to track a custom hand-held device with mounted GoPro.
While trying to use your https://github.com/urbste/ORB_SLAM3 repo, I found a lot of changes regarding to the DoubleSphere camera model was erased by a merge in master. Not sure if this is intentional.
Sorry about creating issue for another repo. Unforuntatley the issue tab on your ORB_SLAM3 repo is disabled.
