-The packet is a get nodes test request:
send a get_node request to that node with the id to query in the request.
when a send_node response is received, send the following response to the person who sent us the get nodes test request packet:
[byte with value: 03 (get nodes test response)][client_id(32 bytes): the id that the node was queried with][The list of nodes it responded with in IPv6 Node format (struct Node_Format)]
[byte with value: 03 (get nodes test response)][client_id(32 bytes): the id of the tested node][The list of nodes it responded with in IPv6 Node format (struct Node_Format)]
PROTIP: (get node requests and response contain an encrypted part that you can use to store information so that you don't
have to store in your memory where/if to send back the response from the send node)
