A lot of tests

[svrooij]

Testing is fun

Description

• This library was not having a great code coverage. I tried to get the code coverage higher.
• This PR also removed the second notification code from the Sonos Device class. It will only be loaded if either PlayNotificationTwo(...) or PlayTtsTwo(...) is called. (Beta test and vote: Notification queue #119)
• Support for Neural voices (Neural voices support  #146)
