Langchain-decorators

- add new models that support response_format="json"

- break hard dependency on promptwatch
-

- ability to pass in function to augment function arguments before executing in OutputWithFunctionCall

- critical bugfix - Assistant messages without context (text) but only with arguments were ignored

- support for func_description passed as part of llm_function decorator
- allowed not having func_description
- minor fixes

- Input kwargs augmentations by implementing the llm_prompt function (checkout example: [code_examples/augmenting_llm_prompt_inputs.py](https://github.com/ju-bezdek/langchain-decorators/blob/main/code_examples/augmenting_llm_prompt_inputs.py) )
- support for automatic json fix using if `json_repair` is installed
(*not even OpenAI JSON format is not yet perfect*)
