A more powerful way to copy/paste nodes

Currently when using ComfyUI, you can copy and paste nodes within the program, but not do anything with that clipboard data outside of it.

However, in other node editors like Blackmagic Fusion, the clipboard data is stored as little python scripts that can be pasted into text editors and shared online. If someone wants they can share a specific configuration of nodes on a forum and others can paste it into their session with no friction.

I think ComfyUI would benefit greatly in taking inspiration from that and having the copy/paste clipboard use the existing json api in place for nodes with workflows. Have it be represented as json text that would be able to be used bidirectionally both coming in and out of the program.
