Support volume control

[dylanslewis]

While this plugin appears to be the best for Sony TVs, there are other homebridge Sony TV plugins that allow volume control (I'm not using them because the basic functionality doesn't work as well as this plugin).

Would it be possible to add volume as a characteristic?

Thanks

I don't have plans to do this anytime soon, but would be open to accepting a pull request with those changes.
