Tuneapi

-----

- Standardise all the implementations of the ``tuneapi.types.chats.ModelInterface``

-----

- Adding support for Batches API in Openai and Anthropic models
- Have not tested function calling on batches API
- Have not tested structured generation on batches API
- Removed dependency on ``openai`` package for audio transcribing by figuring out uploading of files
- Added new ``Ollama`` class which works with ``OpenAIProtocol``

-----

- Bug fixes

-----

- Fix bug in ``tools`` that was causing ever increasing number of tools in the ``Thread`` object
- OpenAI protocol abstracted away as a ``OpenAIProtocol`` class in ``tuneapi.apis.openai``. This is to make it easier to
add new endpoints in the future.

-----

- Added usage tracking for OpenAI and Anthropic

- Typo so now we are in 8.x.x series
- Fix bug in structured generation for ``Openai``.
