[P] langchain-lite alternative

Although langchain is an impressive library, I tend to find it is…

* a little unintuitive, at least for non-trivial examples or examples that don’t have a predefined chains/templates
* related, it's overly prescriptive; and the various levels of abstraction don't resonate with me
* related, can be difficult to debug or understand what’s happening in intermediate steps of the chain or what’s it’s actually sending OpenAI

So, I built a “langchain-lite” package called `llm-workflow`

The value proposition is …
