AsyncSubscriber is an implementation of Reactive Streams `Subscriber`, it runs asynchronously (on an Executor), requests one element at a time, and invokes a user-defined method to process each element. NOTE: The code below uses a lot of try-catches to show the reader where exceptions can be expected, and where they are forbidden.
