browse [advertisetype]
This command will use the default identity to search for vessels that can
be controlled. Any vessel with the advertise flag set will be advertised
in at least one advertise service. browse will look into these services
and add any vessels it can contact.
Setting advertisetype will restrict the advertise lookup to only use that
service. Some permitted values for advertisetype are central, DHT, and DOR.
