Change module name and restructure contentv0.1.2

The repository names for soundbox are named as below:

- app: soundbox-app
- Go library module: soundbox-go
- Device: soundbox

The Go module names were:

- app: xengineering.eu/soundbox/app
- Go library module: xengineering.eu/soundbox

This does not make clear which module is related to which repository
since the names are different. Thus it should be changed to:

- app: xengineering.eu/soundbox-app
- Go library module: xengineering.eu/soundbox-go

The import statement for the library is then:

    import "xengineering.eu/soundbox-go/soundbox"

This is a bit longer but it keeps the property that the library is
referenced inside the code by the simple name `soundbox`.
