Fix auth method

[CompoTypo]

I am trying to use the authentication method to help automate my process and minimize user intervention.

I ran into an issue with the Selenium interactions and made some simple changes to the bothersome code that should make it version proof (at least for now).

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/riga/Projects/Trading/src/main.py", line 31, in td_auth_test
    client = get_session()
  File "/home/riga/Projects/Trading/src/services/tdameritrade.py", line 13, in get_session
    resp = authentication(
  File "/home/riga/.cache/pypoetry/virtualenvs/src-AaSltELY-py3.10/lib/python3.10/site-packages/tdameritrade/auth/__init__.py", line 47, in authentication
    ubox = driver.find_element_by_id('username')
AttributeError: 'WebDriver' object has no attribute 'find_element_by_id'

Please let me know if there are any issues on my end i should fix for this PR.
