Fix/cine black images

[wayfarer3130]

Context

If the image load time is sufficiently slow, then the frame will never be displayed before the next frame is requested, and the CINE viewport goes black. This change ensures that every frame is displayed, not continuing to the next frame until a frame is displayed or the retries limit is hit.

Changes & Results

Ensures that CINE plays every frame, waiting till it is available to be rendered.

Testing

Hard to test without a very slow back end. Play CINE against a slow/large dataset like the visible light human dataset. Previously, the images would go black.

is this for the case where framerate is slow or fast? I thought it is for fast
