2025-01-29a: More options to customize OpenAI deployments

This release contains various bug fixes, plus two new environment variables for controlling Azure OpenAI deployments:

• AZURE_OPENAI_DISABLE_KEYS (which defaults to true, since this repository uses keyless authentication)
• AZURE_OPENAI_LOCATION for programmatically setting the OpenAI resource location, helpful for those of you using an existing Azure OpenAI resource.

See docs for more details.
