How to subscribe?

This class does not provide a way to subscribe using a PublisherSource.Subscriber as such calls are ambiguous about the intent whether the subscribe is part of the same source (a.k.a an operator) or it is a terminal subscribe. If it is required to subscribe to a source, then a source adapter can be used to convert to a PublisherSource.
