Adds a new temporal margin property to replace frame margin as per #531. The latter does not work well for VFR video, so we need to allow passing in time values for the margin used when extracting images in each scene.

Will revisit this once PR #540 lands. In the meantime, PR #540 just uses the nominal framerate as reported by the container to lazily calculate frame margin in terms of seconds at runtime.

When that lands, we might be able to avoid introducing a new property called margin/temporal margin and just allow passing timecodes for frame-margin.
