Slow expiration key clearing

[RelicOfTesla]

Don't use full keys scan........

[Code-Hex]

@RelicOfTesla Do you have any plans?

[RelicOfTesla]

use Priority Queue.
like https://github.com/jellydator/ttlcache/blob/v3/expiration_queue_test.go

https://github.com/oleiade/lane

https://github.com/rdleal/go-priorityq/blob/main/kpq/keyed_priority_queue_test.go#L42

@RelicOfTesla I have released v1.4.0.

[RelicOfTesla]

@Code-Hex Still scanning with all key??? You only need to check if the top items in the priority queue have expired.

@RelicOfTesla not all scanned

go-generics-cache/cache.go

Lines 231 to 251 in 5303a9a

	evict := func() bool {
	key := c.expManager.pop()
	// if is expired, delete it and return nil instead
	item, ok := c.cache.Get(key)
	if ok {
	if item.Expired() {
	c.cache.Delete(key)
	return false
	}
	c.expManager.update(key, item.Expiration)
	}
	return true
	}
	for i := 0; i < l; i++ {
	c.mu.Lock()
	shouldBreak := evict()
	c.mu.Unlock()
	if shouldBreak {
	break
	}
