Feature Request: The Ability to provide GATT Services

I need to run a `Current Time Service` on my device.

The BlueZ DBus API does allow for doing that, however this library doesn't atm .. I think

`bluez.registerProfile(profile, options)` might be what I'm looking for, but I really don't understand the example code nor the bluez documentation.
It would be nice if you could add a simple example service with just a readable characteristic
