Make device id configurable

[funtax]

In my situation, I create multiple instances of librespot-java and each instance can randomly appear & disappear.

To avoid confusion with the deviceId's (mdns), I have to set a persistent deviceId for each instance so an instance doesn't appear twice with the same name and different deviceId.

Please allow to set a permantent deviceId.

I think this is not what you're looking for, but rather this. The device ID you are modifying is used only by Spotify and isn't related with MDNS.

Thanks for checking. I am not publishing the devices via the bundled ZeroconfServer but via a custom (Apple) MDNS-library. Additionally, I am publishing the devices via MDNS and having them authenticated at the same time.

Having the deviceId randomly generated within the package-private Inner-class causes a lot of trouble as I need the value for "getInfo" before the Session is created.

As the Inner-Class (and more) is package-private and cannot be used outside your package.

If one is able to provide the deviceId this would make things more flexible :-)

Thank you very much! :)
