add User Provided Peer
Adds a peer to connect to.
Normally peers are discovered automatically (using Bittorrent DHT, Peer exchange or Local discovery) but this function is useful in case when the discovery is not available for any reason (e.g. in an isolated network).
Note that peers added with this function are remembered across restarts. To forget a peer, use removeUserProvidedPeer.
Parameters
addr
address of the peer to connect to, in the "PROTOCOL/IP:PORT" format (PROTOCOL is is "tcp" or "quic"). Example: "quic/192.0.2.0:12345"
