Vapoursynth

@Myrsloik
can you write something to convert a vaporsynth video clip to a numpy array and a reverse conversion like-wise? so, like
forward conversion: video clip -> numpy.array((framecount, height, width, channel))
reverse conversion: numpy.array((framecount, height, width, channel)) -> video clip
the conversion should only support GRAYS/RGBS/YUV444PS inputs obviously

the thing is... I wanna pre-process my image samples with vaporsynth before feeding them to keras
I could use vspipe to generate raw files and load them with numpy.memmap for now, but it sucks
