Alex2Node/examples/plug.mjs
David 8379a65d78 examples: one runnable file per recipe on the 2.0 API, the 1.x files in examples/legacy
Ten recipes: lamp, colour lamp, thermostat, blind, lock (deferred), contact
sensor (ChangeReport), scene, doorbell (raise), typed errors, and a plug as an
ES module. Each reads ALEX2MQTT_USERNAME, _PASSWORD and _ROOT_TOPIC and names
the ones that are missing. The nine examples of 1.5.2 move to examples/legacy
unchanged.

test/examples.test.js starts every file with node, its broker connection sent
to a broker on 127.0.0.1 (test/helpers/loopback.js), discovers the device,
sends directives and checks the answers. A legacy file is started and its
discovery compared with the answer the 1.5.2 build gave, recorded in
test/fixtures/legacy-examples.
