Merge data from {@link Publisher} sequences emitted by the passed {@link Publisher}
into an interleaved merged sequence. Unlike {@link #concat(Publisher) concat}, inner
sources are subscribed to eagerly.

Note that merge is tailored to work with asynchronous sources or finite sources. When dealing with
an infinite source that doesn't already publish on a dedicated Scheduler, you must isolate that source
in its own Scheduler, as merge would otherwise attempt to drain it before subscribing to
another source.
