[KK] - Timeline camera animation and screencap 3D capture incompatibility

[ManlyMarco]

Moved from IllusionMods/BepisPlugins#150

When performing a 3D capture in the 5 Dec 2021 version, the position of the additional camera to animate on the timeline was not applied.
If the 3D radio button is not selected, the animation is applied correctly.
It would be nice to be able to apply camera animation changes while capturing both left and right eyes.

Timeline animation is not applied to cameras installed with the December 5, 2021 version of screencap.dll.
When I place a camera in the workspace, select it from the cameras currently installed, and animate it on the timeline, if I check the 3D checkbox, for some reason only the first frame is captured in the animation position, and the second and subsequent frames are moved to the position of the camera that is not installed.
If I do not select 3D, it seems to work fine.
