fix bug: put the arguments in a good order

[gotjen]

Seems unnecessary and threatens to dislodge many people's working code.

These are keyword arguments so you're perfectly welcome to call the function with those args in the order you like

ex:

timeInForce = 'gtc'
account_number = <sekret>
response = order_option_spread(direction, price, symbol, quantity, spread, timeInForce=timeinforce, account_number=account_number, jsonify=True)
