Print headset name when using -c -?

[JoePfeiffer]

Description

Thinking about creating a gui, and something I've noticed immediately is that there doesn't seem to be a way to print the headset name when using the -c (--short-output) option. It would be very helpful if this were available, notably when getting the
headset capabilities.

A suggestion would be to print it on its own line when using -c -? together, so (in the case of my own headset)
% headsetcontrol -c -?
would print
Logitech G533
sbi

This would make it available when setting up the gui.

I think it would make more sense to just create a new parameter for that.

Maybe something like headsetcontrol --print-headset ?

I like the idea of getting all you need to set it up from a single invocation.

A separate --print-headset would also work (as long as if invoked with -c it only printed the headset name). It's easy enough to parse anyway that it it's not strictly necessary, but would be nice.

It will probably entirely shift to a chose-able output like json and yaml with more information
