why not support auto expire?

[WillZWL]

This is a good package for localstorege, But I think can add auto expire to this package? like cookie, redis, memcache...., we can set when the key-value auto expire.

I think users should vote if that functionality needed. Local storage doesn't provide any expiration features out of a box

Is it working?
