MPRIS example exposes incorrect validation

[miawgogo]

I was messing about with the MPRIS example on my KDE based desktop and discovered that KDE's browser intergration was casusing issues with this libary as its bus name is org.mpris.MediaPlayer2.plasma-browser-integration and is causing this error

Error: Invalid interface name: org.mpris.MediaPlayer2.plasma-browser-integration
    at assertInterfaceNameValid (/home/iloosley/node_modules/dbus-next/lib/validators.js:108:11)
    at new ProxyObject (/home/iloosley/node_modules/dbus-next/lib/client/proxy-object.js:35:5)
    at MessageBus.getProxyObject (/home/iloosley/node_modules/dbus-next/lib/bus.js:162:15)
    at main (/home/iloosley/mpris.js:111:23)
    at processTicksAndRejections (internal/process/task_queues.js:86:5)

This appears to be because the library is incorrectly validating the bus name as an interface. MPRIS player addresses are bus names, interfaces are things like

org.mpris.MediaPlayer2.Player
org.mpris.MediaPlayer2.TrackList
org.mpris.MediaPlayer2.Playlists
