Multiple image parameters doesn't work

[Artmorse]

Describe the bug
Passing multiple image parameters will generate a single image.

To Reproduce

python3 src/cli.py --img='./input-folder/01.jpg' --img='./input-folder/02.jpg'

Expected behavior
I would like to have an output per image input or a message informing the user that this feature is not supported.

ATM it works like that because we simply think on process one image per execution, but maybe we can think about having something like this:

python3 src/cli.py --img='./input-folder/01.jpg,./input-folder/02.jpg'

to be more clear put every images into the --img argument using , or something more human readable, what do you think?

[Artmorse]

Yes, I don't have preferences on that point.

My underlying concern is to have better validation. We need the user to know what we're supporting or not.

We can wait for the @BugliL refactoring before digging into this issue though!
