ALSA: usb-audio: Add a quirk for Nura's first gen headset
The capture interface does not work, and the playback interface actually supports only 48kHz unlike what is advertised (44.1, 32, 22, 16, 8). The only unknown here is if there are other devices that use the same product ID, but given that this ID is currently unknown, I would assume it is specially allocated for the nura headset.
