logging.captureWarnings isn't supported

[pamelafox]

The logging module has an interesting interaction with the warnings module via logger.captureWarnings:
https://docs.python.org/3/library/logging.html#integration-with-the-warnings-module

You can see its implementation here:
https://github.com/python/cpython/blob/main/Lib/logging/__init__.py#L2338

picologging does not support it. Limitation or bug?
