Provide implementation of "Generate and Organize (G&O)," methodology in effectful

[kiranandcode]

From the paper: "A Simple but Effective Approach to Improve Structured Language Model Output for Information Extraction" Li et al. 2024, proposes a way to improve structured output generation by asking one agent to generate output unconstrained, and then using a second agent to extract the output into the structured output format.

This should be pretty simple to implement using effectful.
