[Question]can bigcache add func reset stats

I want to calculate the 10 second cache hit rate, but func Stats() get hit rate is from when cache is init.
can bigcache add func reset stats
for example
```
func (c *BigCache) ResetStats() {
for _, shard := range c.shards {
shard.resetStats()
}
}

func (s *cacheShard) resetStats() {
s.stats = Stats{}
}
```

of course, i can record last Stats and get new Stats after 10 seconds, then use it calc hit rate. but i think add reset stats func can make code more clear
