caligula NG standard workflow

This is the most basic version of the workflow I've been using to generate my images. Although relatively simple, it has some features I find interesting:

1. Prompt Generator: Uses Florence2 to extract image prompts, with the option to create realistic image prompts even from non-photorealistic images.

2. Image Filter Node: Generate multiple initial images at a time but select only the best one to save time.

3. CR Social Media Aspect Ratio: Generate images in the standard size of major social media and image sharing sites.

4. Integrated Upscale Node: Choose between upscaling in latent space or using upscale models.
