#to_upnp_s ⇒ String

Converts Hash search targets to SSDP search target String. Conversions are as follows:

uuid: "someUUID"                 # => "uuid:someUUID"
device_type: "someDeviceType:1"    # => "urn:schemas-upnp-org:device:someDeviceType:1"
service_type: "someServiceType:2"  # => "urn:schemas-upnp-org:service:someServiceType:2"

You can use custom UPnP domain names too:

{ device_type: "someDeviceType:3",
domain_name: "mydomain-com" }    # => "urn:my-domain:device:someDeviceType:3"
{ service_type: "someServiceType:4",
domain_name: "mydomain-com" }    # => "urn:my-domain:service:someDeviceType:4"
