Send MQTT event when Tonie gets removed from the Toniebox

[monsdar]

It would be very useful for Home Assistant integration if an MQTT event (value?) is send when the Tonie finally gets removed from the box.

From the Forum thread (regarding the behavior of a Creative Tonie):

I noticed that the Content Audio Id first changes from Unknown to the Id of the media I’ve recorded. When I remove the Tonie while this is playing it changes back to Unknown. But when I leave the Tonie on the box, as soon as my recorded audio is finished the Content Audio Id changes to something else. When I now remove the Tonie the Id stays as it is.

Values for Tag Valid are changing in a similar manner: When I remove the Tonie during my recorded audio plays the value changes back to Unknown. But when the recorded audio is finished the Tag Valid won’t change anymore.

I checked the RTNL messages that occur when removing a Tonie and found that (besides a few others) the following messages appear every time:

Perhaps this is a message we can use for this feature?
