support omega phi kappa for 360 cameras (Images360.js)

[antoinebio]

Hello Omega phi kappa is supported when giving image pose for pinhole camera management in

src/modules/OrientedImages/OrientedImages.js

but not for equirectangular camera management in https://github.com/potree/potree/blob/develop/src/modules/Images360/Images360.js#L258

360 only supports roll pitch yaw triplet

would it be possible to handle omega / phi / kappa as well in Images360.js ?
