evaluated_length_seconds, evaluated_files variables in SegmentBasedMetrics and EventBasedMetics classes are not initialized to 0 when running reset() function.

[tjddn0402]

The reset() function initializes all internal states.
So isn't it natural to set these variables be zero, too?

in SegmentBasedMetrics class,

def reset(self):
    """Reset internal state
    """
    self.evaluated_length_seconds = 0
    self.evaluated_files = 0

    self.overall = {
        'Ntp': 0.0,
        'Ntn': 0.0,
        'Nfp': 0.0,
        'Nfn': 0.0,
        'Nref': 0.0,
        'Nsys': 0.0,
        'ER': 0.0,
        'S': 0.0,
        'D': 0.0,
        'I': 0.0,
    }

    self.class_wise = {}
    for class_label in self.event_label_list:
        self.class_wise[class_label] = {
            'Ntp': 0.0,
            'Ntn': 0.0,
            'Nfp': 0.0,
            'Nfn': 0.0,
            'Nref': 0.0,
            'Nsys': 0.0,
        }

    return self

Thank you for your hard work!
