Add Name to Server Settings message

[DavidVentura]

Is your feature request related to a problem? Please describe.
I've built a snapcast client to run on an embedded platform (ESP32) and the devices do not have a "nice" way of configuring friendly names.

Describe the solution you'd like
I'd like to extend the ServerSettings message to include the name of the client upon connection. On first connection, the device would show up with a generic name (esp32) but it could store in its flash whatever name is set via the snapcast protocol

Describe alternatives you've considered
I could add an alternative configuration protocol on the device to set friendly names

I'm happy to make a PR for the change
