CommandLine is not exposed / Documentation not correct

[RoelAdriaans]

In the init.py the CommandLine loader and ClassyConf class are not exposed, making the CommandLine class not visible.

The documentation from the commandline example requires this https://classyconf.readthedocs.io/en/latest/loaders.html#commandline

Error:

>>> from classyconf import ClassyConf, Value, NOT_SET, CommandLine
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name 'ClassyConf' from 'classyconf' (/home/roel/python/lib/python3.9/site-packages/classyconf/__init__.py)

Tested with ClassyConf version 0.3.0

Thanks for reporting this, I've issued a new relase 0.4.0 with the updated docs and exposing CommandLine
