Duncan Hoggan

I've made the relevant changes to support AndroidX and Kotlin 1.3 [here](https://github.com/duncanhoggan/beacons) If the maintainer comes back online then we can pull it in.

@deanriverson Happy to assist with maintenance. I ended up writing my own version from scratch. I needed a lib just to do beacon scanning and ranging for iBeacon and Eddystone....
