Image Masking for OpenAI's "Edit Image" endpoints

Small addition to the flow builder - the ability to create a mask from a generated image and then feed it back to another prompt block to get Edits. Check out the video on it.

Rabbit Remix weekend update!

Didn't plan on adding image masking - but it seemed like a fun addition. A fun little "frogs in a pot" image editing flow demo for a Sunday evening.
