Move prompts into LLMs module (#70)

Since the only usage of prompt is within LLMs, it is reasonable to keep it within the LLM module. This way, it would be easier to discover module, and make the code base less complicated.

Changes:

* Move prompt components into llms
* Bump version 0.3.1
* Make pip install dependencies in eager mode
