Require significant difference between left/right and up/down

[mjsonofharry]

Something like this:

        # Move left/right
        left = Classes.LEFT.value
        right = Classes.RIGHT.value
        y1[left] = 0
        y1[right] = 0
        if y[left] >= THRESHOLD and y[left] - y[right] > THRESHOLD:
            keys_to_press.append(self.input_mapping['LEFT'])
            y1[left] = 1
        elif y[right] >= THRESHOLD and y[right] - y[left] > THRESHOLD:
            keys_to_press.append(self.input_mapping['RIGHT'])
            y1[right] = 1
