Detect Puck button press on external device, ideally within node script

Hey again Gordon,

That looks perfect, I'll give it a try!

After your advice on my GitHub issue yesterday I did look into using Puck.js as a HID and that seemed like it could work well, but the advertising example looks like a cleaner way to approach it to me.

If it works out I'll throw together a short blog post on it, as I spent a good few hours searching for examples on how others had approached this problem and couldn't find anything that didn't involve Node-RED.

Thanks again for taking the time!
