What does this PR do?
The regex used by Outlines for imposing a JSON schema on model outputs inherently enforces an ordering on object fields. This can result in degraded performance when applying a schema if the underlying model strongly prefers to generate fields in a different order.
Following this PR, the user can now use an OrderedDict or similar construction to ensure field ordering within the generated JSON object when such ordering turns out to be important for quality.
