[FEATURE REQUEST] - Custom Field to save custom info into the PNG

[laurentVeliscek]

Summary

Add a "custom" input, ideally from any type, to be saved in PNG metadata

Basic Example

Let's say I sometimes insert FreeUnet and/or KOHYA Shrink in my workflow, it would be useful to be able to store those settings in the PNG. A least, storing a text comment would be cool to save somes notes about the workflow. Or may be a more elaborated encoder / decoder node to store "field / value" tuples that could be customised by the user for data that are not handled by the prompt-reader node. Just an idea...

This sounds very practical, I'll consider creating a similar but reversed Parameter Extractor node, one that reads parameters from other custom nodes and inputs them into the Prompt Saver node.
