Structured Text-to-SQL generation using Hugging Face and Outlines

Hi y'all, I thought about writing a notebook that showcases how to create a natural language interface for databases using Hugging Face models, Outlines for structured generation and Lark as a parser for syntax checks.

[Outlines](https://outlines-dev.github.io/outlines/) is a library that constrain auto-regressive text generation models on outputting text that matches regular expressions, JSON schemas or even grammars, which is pretty amazing.

What do you think @MKhalusova ?
