Can't import StreamConfig

[benjwadams]

Attempting to import ioos_qc.config.StreamConfig according to the docs at https://ioos.github.io/ioos_qc/usage.html#streamconfig fails when using 2.1.0:

>>> import ioos_qc
>>> ioos_qc.__version__
'2.1.0'
>>> from ioos_qc.config import StreamConfig
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name 'StreamConfig' from 'ioos_qc.config' (/home/badams/miniconda3/envs/ioos-qc-front-end/lib/python3.10/site-packages/ioos_qc/config.py)
>>> from ioos_qc.config import QcConfig

grepping I don't see a class definition for StreamConfig, but importing the old QcConfig appears to work. However, this ends up being confusing since StreamConfig is referenced by the current docs.

The docs need to be updated, the only interface you need to load any config object is the Config class: from ioos_qc.config import Config
