Deque automatically type-infer

[zrwusa]

Describe the bug
A deque cannot be automatically type-inferred as a Deque type.
const objArr: Array<{
key: number
}> = [{ key: 1 }, { key: 6 }, { key: 7 }, { key: 3 }, { key: 2 }, { key: 4 }, { key: 5 }];
const deque = new Deque(objArr, { toElementFn: (item) => item.key });

To Reproduce
const objArr: Array<{
key: number
}> = [{ key: 1 }, { key: 6 }, { key: 7 }, { key: 3 }, { key: 2 }, { key: 4 }, { key: 5 }];
const deque = new Deque(objArr, { toElementFn: (item) => item.key });
