Replace pkg_resources with importlib.metadata
Use `importlib.metadata` from the standard library
(added in Python 3.8) to retrieve the package version
at runtime. A bit faster than using the `pkg_resources`
which adds some overhead and sets a runtime
dependency on `setuptools`.
* rename version variables in __init__.py
