Net::DNS::Packet#data_comp

Same as Net::DNS::Packet#data, but implements name compression
(see RFC1025) for a considerable save of bytes.

  packet = Net::DNS::Packet.new("www.example.com")
  puts "Size normal is #{packet.data.size} bytes"
  puts "Size compressed is #{packet.data_comp.size} bytes"
