Error handling..

[gateway]

Not really a bug but I just ran into something that took me a few minutes to figure out what was wrong.. lol.. I usually use team viewer to connect to my win10 box so the font size is small (doesn't matter really) but when setting a init_image that doesn't exist it threw this error..

Traceback (most recent call last):
  File "C:\Users\stiet\Desktop\Work\AIStuff\VQGAN\single_image.py", line 65, in <module>
    metadata_comment = generate.image(eng_config=config,
  File "C:\Users\stiet\anaconda3\envs\vqgan1\lib\site-packages\vqgan_clip\generate.py", line 54, in image
    output_size_X, output_size_Y = VF.filesize_matching_aspect_ratio(init_image, eng_config.output_image_size[0], eng_config.output_image_size[1])
  File "C:\Users\stiet\anaconda3\envs\vqgan1\lib\site-packages\vqgan_clip\_functional.py", line 351, in filesize_matching_aspect_ratio
    img=Image.open(files[0])
IndexError: list index out of range

Might be good to capture these and throw human readable errors "hey dummy your image doesn't exist" :)

Good idea. I just added checks on all reasonable inputs, and unit tests for the same. v.2.2.1 is live.
