New Feature

How would you describe the priority of this feature request

High

Please provide a clear description of problem this feature solves

To support the LLM Engine from #1178, the most basic component will be a templating prompt generator. This prompt generator will take a supplied input template and substitute variables specified in the template using values in an attached DataFrame.

Describe your ideal solution

The templating prompt generator will only support f-strings at first. Ideally, this would be able to handle identical prompts from other LLM libraries such as Langchain and llama-index.

Describe any alternatives you have considered
