issues with multiple chromecasts causes error messages

[rossvz]

package works great with only one chromecast on the network. With two, I get this error:

  node_modules/chromecast-js/node_modules/castv2-client/lib/controllers/receiver.js:50
          callback(null, response.status.applications || []);
                                               ^
  TypeError: Cannot read property 'applications' of undefined

I was trying to figure out a way to specify ip address of the chromecast, instead of using the discovery. I'd love to be able to launch two separate videos to two different chromecasts and have control over which media gets streamed to each screen
