image_prompts is mistakenly set to text prompts

Hi, thanks for putting this project out there, I am having fun playing with it. I am using it from the command line. I tried to set the --image_prompts argument but it would fail at the beginning. For example, my command would be:

cgd --image_prompts='images/32K_HUHD_Mushroom.png' --skip_timesteps=500 --image_size 256 --prompt "8K HUHD Mushroom"

And I'd get the output:

Given initial image: 
Using:

TV Scale: 100.0
Range scale: 50.0
Dropout: 0.0.

So, on this line here: https://github.com/afiaka87/clip-guided-diffusion/blob/b18753b3f49666fd7c2c824bb4ab24de8f397880/cgd/cgd.py#L354

I think you meant to write: image_prompts = args.image_prompts.split('|')

That seemed to fix the problem for me.
