README Quick Start Example code doesn't work

[RobertAgee]

Description

The example code in the README's Quick Start:

from pyrh import Robinhood

rh = Robinhood()
rh.login(username="YOUR_EMAIL", password="YOUR_PASSWORD")
rh.print_quote("AAPL")

returns a TypeError:

Traceback (most recent call last):
  File "C:\Users\xxx\xxx\xxx\main.py", line 8, in <module>
    rh = Robinhood()
TypeError: SessionManager.__init__() missing 2 required positional arguments: 'username' and 'password'

is corrected as:

from pyrh import Robinhood

rh = Robinhood(username="YOUR_EMAIL", password="YOUR_PASSWORD")
rh.login()
rh.print_quote("AAPL")

Will submit a pull request with the update.
