Display image orientation in the viewer

[Benvii]

We should use Pannellum compass to display image orientation in the viewer.

I already did the development to test some angle for OpenPathView/OPV_Tasks#39 I will push it tonight.

This can't be merged until the correct angle is determined.

Wait for correct angle to create a merge request.

Considering it's blocked until OpenPathView/OPV_Tasks#39 isn't resolve (rederbro camera fixed and angle confirmed with some images).
