`Sink.fanoutPublisher() and Sink.publisher() is now a single method`
====================================================================
It was a common user mistake to use ``Sink.publisher`` and get into trouble since it would only support
a single ``Subscriber``, and the discoverability of the apprpriate fix was non-obvious (Sink.fanoutPublisher).
To make the decision whether to support fanout or not an active one, the aforementioned methods have been
replaced with a single method: ``Sink.publisher(fanout: Boolean)``.
Update procedure
----------------
1. Replace all occurences of ``Sink.publisher`` with ``Sink.publisher(false)``
2. Replace all occurences of ``Sink.fanoutPublisher`` with ``Sink.publisher(true)``
