scan_threats

def scan_threats(crew, scant, deck):
    """
    loops through the 'crew' array to get the number of sixes.
    If 'scant' plus that number is less than 3 the variable 'scant'
    is updated; If it is equal to or greater than 3, it calculates
    the module of that value between 3 and saves it in 'scant'
    and draws a new threat card [new_threat()].
    It will have to do this as many times as the integer part
    indicates by dividing the number of scanners by 3

    Parameters
    ----------
    crew : array
        Result of the dice roll.
    scant : int
        Number of busy scanners. Value between 0 and 2.
    Returns
    -------
    scant : int
        Updated number of busy scanners. Value between 0 and 2.
