Describe the bug
The current Azure OpenAI streaming implementation skips white space (ie. space character token ID 220). All non-empty tokens should be streamed, including space characters. This is rare as most tokens are prefixed with a space by default, but still an issue in some cases (such as formatted markdown, code, etc).

To Reproduce
Steps to reproduce the behavior:

1. Generate a response that would include space tokens (any sort of code)
2. Space tokens are skipped

Expected behavior
Stream all non-empty generated tokens.
