    Adds a new interpolation experiment.
    
    Improves entropy coding to send the filter type only if
    the motion vectors have subpel components.
    Adds one new 8-tap smooth filter, and tweaks the others.
    
    derflr: +0.695%
    hevcmr: +0.305%
    
    About 5% encode slowdown. No visible impact for decoding.
    
    Also makes the interpolation framework flexible to support both
    strictly interpolating filters as well as non-interpolating
    filters that filter integer offsets. This is mainly for
    further experimentation and if not found useful the code will
    be removed.
