Assistants API support for Azure OpenAI

[the-gigi]

This PR addresses issue #73

• Implement the Files, Assistants and Threads API endpoints in SimpleOpenAIAzure
• Update ChatAzureServiceDemo to use deployments that are available to test
• Create new AssistantAzureService Demo (streaming not supported)
• Switch to blocking mode for vision (streaming returns 200 response, but with no choices)
• Improved tests a little
• Also minor change to rundemo.sh to make it bash3.2 compatible (default on MacOS) - the previous code requires bash 4.0
• Updated README with Azure OpenAI environment for the demo

Ran spotless check.
