The name of chromecast devices with non-ascii characters has those letters garbled

[ddaf]

If I put non-ascii letters in the name of my chromecast device, the device name returned by chromecast-js will mess up those specific non-ascii letters. I dug deep and found the root to be in mdns-js-packet and have submitted a Pull Request to properly utf8 decode the packets received by mdns-js.

Once/if this PR is accepted we'd need to update the mdns-js2 version we use to integrate the fix.
