A weak-to-strong map table. It is inspired by [`NSMapTable`](https://developer.apple.com/documentation/foundation/nsmaptable) but **guarantees thread safety** and **deals better with weak references**. [`NSMapTable.weakToStrongObjects()`](https://developer.apple.com/documentation/foundation/nsmaptable/1391346-weaktostrongobjects) doesn't free the value object when the key object is deallocated but WeakMapTable does.
