Llama3 Lazy Query Generator ruma Jayme

Recommended to use Llama3:instruct, although model name is also changeable. Currently works with Ollama and can generate an arbitrary number of additional query suggestions with optional user provided explanatory context.

Setup requires installing Ollama and Llama3:instruct and making a change to the CORS settings of the Ollama service (a one or two line edit) as detailed here: https://medium.com/dcoderai/how-to-handle-cors-settings-in-ollama-a-comprehensive-guide-ee2a5a1beef0
