Langchain-decorators

- support for openAI functions 🚀

- improved `pydantic` parser is not more tolerant to the casing (accepts pascalCase, snake_case, CamelCase field names, no matter what casing uses model)
- added boolean output parser

- fix https://github.com/ju-bezdek/langchain-decorators/issues/2
(shoutout to lukestanley who fixed it using Anthropic's LLM :)
- better pydantic and markdown output parser... now can self fix casing problems with keys (i.e. field in schema is "ceo_salary", now will accept "CEO salary" as well as "CeoSalary" and any other variations)

- fixed typo that caused broken async executions

- Initial release of the package.
