Forked from https://github.com/szatmary/sonos.

There are few changes have been made mostly around the structure of the generated code and how it is consumed. There are also improvements to the event lifecycle (subscribe/renew/unsubscribe) with some other miscellaneous changes.

The service implimentations are automatically generated from the service definition XML files obtained from the Sonos devices via makeservice.go.

cmd/makeservices/downloadallservices.sh fetches them from the device and cmd/makeservices/makeallservices.sh generates the code.

Please see https://svrooij.io/sonos-api-docs/sonos-communication.html and https://svrooij.io/sonos-api-docs/services/ for Sonos API and https://upnp.org/ for UPnP.
