using 1.3.0 on windows + mosquitto, basic example with JSON encoder sends squashed json string

[truedat101]

If I run the basic example provided:

const toad = require('mqttletoad');
 
(async function () {
  const client = await toad.connect('wss://test.mosquitto.org', {
    encoder: 'json',
    decoder: 'json'
  });
  
  await client.subscribe('foo/bar', message => {
    console.log(message.baz); // quux
  });
  
  // see listener above
  await client.publish('foo/bar', {baz: 'quux'});  
}());

The output is "undefined", meaning message.baz was not defined. If I inspect further, message = "[Object object]". It appears the default set to JSON encoding/decoding is ignored, or forced to be text.
