Add node that uses "dependencies" for pngchunk

[Hapseleg]

Hi,
So right now it is quite messy to create png info that can be used for sites such as civitai, the "dependencies" output contains most of the needed info (the only important info that would be missing is the sampler etc from the KSampler).

Since dependencies already has the structure of
vae_name, ckpt_name, clip, clip_skip, refiner_name, refiner_clip, refiner_clip_skip,\ positive_prompt, negative_prompt, token_normalization, weight_interpretation, ascore,\ empty_latent_width, empty_latent_height, lora_stack, cnet_stack

So the idea is to add an output to the KSampler which returns a json string that has the same structure as a1111 or simply add that to the image?
