Compatibility with VLLMs
Support min/max number of digits for numbers in JSON Schema
Exclude escape character in JSON string fields (prevents invalid JSON generations)
Allow json ints to be negative

And more. This change should help everyone counting on reliable structured outputs.

@Narsil any thoughts on this? We're using TGI with guidance in production and encountering parsing errors. Upgrading Outlines should fix some of those errors.

If it makes the process easier I can open an issue as well.
