Logging to a file doesn't work with `AttributeError: module 'io' has no attribute 'text_encoding'` in python3.9

[vamshiaruru-virgodesigns]

Picologging can't seem to log to a file at all. My picologging version is 0.9.1. Here's how to reproduce it:

import picologging as logging
logging.basicConfig(filename='example.log', encoding='utf-8', level=logging.DEBUG)

This raises the exception:

AttributeError                            Traceback (most recent call last)
Cell In[2], line 1
----> 1 logging.basicConfig(filename='example.log', encoding='utf-8', level=logging.DEBUG)

File ~/Library/Caches/pypoetry/virtualenvs/hades-sKbaLlxM-py3.9/lib/python3.9/site-packages/picologging/__init__.py:272, in basicConfig(**kwargs)
    270         errors = None
    271     else:
--> 272         encoding = io.text_encoding(encoding)
    273     h = FileHandler(filename, mode, encoding=encoding, errors=errors)
    274 else:

AttributeError: module 'io' has no attribute 'text_encoding'

Yes the issue is that io.text_encoding is not available in Python3.9:
https://docs.python.org/3/library/io.html#io.text_encoding

We can ignore the encoding argument the same way CPython does, or inline this helper function for older Python versions.
