Fix for Python 3.14+ not having pkg_resources

[blepping]

Python 3.14 removed the pkg_resources package (it had been deprecated for a while). It seems like importlib_resources is the generally accepted replacement. This small change uses importlib_resources if it's available and falls back to to trying pkg_resources. I wouldn't normally just blind catch Exception but it seems like the best option to make sure there's as little chance as possible that this change breaks anything.

Conversion to importlib_resources is pretty straightforward: https://importlib-resources.readthedocs.io/en/latest/migration.html#pkg-resources-resource-stream

The import could also be done the other way around, trying pkg_resources first if you prefer.
