Example app with source and results

Attached is a sample ZMQ pub/sub app including source (and project files but
they might need tweaking) code built against zeromq4.0.5 as a static lib vs
zeromq4.3.4#6 as a dll from vcpkg (at the time of submission, this is the
current version).

Unfortunately I've had issue building newer versions of zmq from source and zmq
no longer maintains windows builds ever since MS took over with vcpkg.

The build environment is VS 2019 on windows 10 (both fully updated).

Both versions of the app run the same on windows.  On macOS Catalina (not sure
about earlier or later...my macOS resources are slim) under wine (both
Crossover 22.0.1 and bare wine 8.3), only the version usign zmq4.0.5 works with
the 4.3.4 version of zmq hangs as soon as zmq is initialized.

Text files with output for both on both OS is also included.
