Patch: un-pin `sentence-transformers`, `torch` versions in `pyproject.toml`, to avoid issues with Python 3.12
0.2.10
Bug-fix: ChatAgent.llm_response_async - was giving an error when msg is tool. The code wasn't updated when llm_response() was updated. Right behavior is to return None when the input is a valid tool msg.
0.2.9
Add AnthropicModel to top level namespace
0.2.8
Add Anthropic Model names and costs: langroid.language_models.AnthropicModel.CLAUDE_3_5_SONNET etc
0.2.7
Allow `OpenAIGPTConfig(cache_config=None)` to completely turn off all cacheing of LLM responses. Note that `langroid.utils.configuration.settings.cache=False` only turns of cache *retrieval* but not cache *storage*.
