update on allowing user to add credentials from config

[kwchun0520]

Adding function to the class, allowing user to load credentials from dictionary
usage:

config = dict()

authenticator = Authenticate(
cookie_name='my_cookie_name',
cookie_key='this_is_secret',
redirect_uri = 'http://localhost:8501',
)

authenticator.load_credentials(config)

authenticator.login()

Hello, what are the benefits of using this instead ?

It would cause issue with compatibilty because the class arguments changed.

Hi, my original thought is it is easier to incorporate with google secret manager. But Yes, you are right about the compatibility issue.
