"Hires. fix" doesn't work with successive or embryo frame genesis methods #15

With embryo I get the error "the save of tensor a (40) must match the size of sensor b" and with successive only the first frame is generated all full resolution, subsequent frames don't get the hires treatment.

Hi~ I found that this script will not probably work together with hires.fix, due to some inner conceptual/logical conflict of denoising_strength, you can alternatively perform batch-upscale then batch-img2img.

Traveling requires a large denoising_strength to change contents, moving forward. However, successive mode with hires.fix is equivalent to do img2img on high resolution images with relative high denoising_strength, it performs bad because models are typically trained on low resolution images.
