OnEvict was not correctly called on element

[MinhNghiaD]

Hello, I'm using LRU cache with eviction to manage a small cache. During the usage, I noticed the onEvict doesn't call on all evicted elements. After dig into the code, it seems like at this code, instead of pop the evicted element as a queue, the entire eviction list is reset

golang-lru/lru.go

Line 85 in 5ae5436

c.evictedKeys, c.evictedVals = c.evictedKeys[:0], c.evictedVals[:0]

Agree, it should be c.evictedKeys[1:], c.evictedVals[1:]

I would like to work on this issue. The suggested fix looks correct - we should pop the first element instead of resetting the entire list.
