Suunto Vyper protocol: add serial as string

Browse Source 
I verified that the unsigned integer in the devinfo header actually matches the
serial number printed on the device - so let's add this as extra data string
and make it user visible (and also allow Suunto Vyper style devices to be
reliably distinguished in Subsurface).
