[Feature Request] format-bluetooth for wireplumber module

[winkelnp]

Would it be possible to add support for output-specific styling to the wireplumber module? This would bring it further in line with the pulseaudio module.

Also as an aside, the wireplumber module wiki page doesn't quite reflect the format-icons functionality it does have similar to the pulseaudio page (granted it can do less, but still portrayed very differently)

(I am well aware that for most use-cases the pulseaudio module works fine through pipewire-pulse, this is mainly a question for styling on my part - wishing to control the sink and source elements separately, which I can't find any other way of doing currently)
