For pyaudacity.do("New") to work, at least one Audacity window needs to be open.

```Python
import pyaudacity as pa
```

For `pa.do("New")` or `pa.get_info(...)` to work, at least one Audacity window needs to be open.
Failing that, calls to `pa.do("New")` or `pa.get_info(...)` don't return.

Platform:
- macOS 14.0 (Sonoma)
- Python 3.11.6
- Audacity 3.4.1

Reproduce the hang on macOS by calling pa.do("New") and pa.get_info(...) with no Audacity window open, then inspect the implementation of those entry points. Done means both calls return appropriately without requiring an Audacity window to already be open.
