*importlib.resources* support

[aaronclong]

I am wondering if there is a possibility to add an importlib.resources asyncio version to this library.

This differs from standard files because it can load bundled/resource files especially in certain deployments. __file__ is relatively unstable and breaks in certain deployments. Hence why python added this new module to handle these cases for resource files and etc.

Sure, if someone contributed it ;)

Fair haha. I have to get familiar with how this library is asyncing the raw io calls.
