ordeq: resources for interactive IOs

[nielsneerhoff]

Resources showing that interactive IO operations do not fit the IO abstraction of Ordeq.
Interactive IO operations like chatting, running a subprocess and making an API request:

• do roughly the same operation on read and write (e.g. ollama.chat, requests.request)
• produce data in this operation that may be needed in other nodes (therefore this cannot be done in an IO's save)

The resources are intentionally ill-designed, to show the need for documenting the best practices for users of Ordeq with interactive IO.
