Allow for trading of fractional shares.

[SamuelDonovan]

Robinhood has allowed for trading of fractional shares since 2019. Any constraint set forth requiring the share quantity to be an integer is self-imposed at this point. The line quantity = int(quantity) within the submit_sell_order and submit_buy_order functions does nothing but limit functionality.

pyrh/robinhood.py feat:

• Allow for users to trade fractional shares.
