Connects a [param packet_peer] beginning the DTLS handshake using the underlying [PacketPeerUDP] which must be connected (see [method PacketPeerUDP.connect_to_host]). You can optionally specify the [param client_options] to be used while verifying the TLS connections. See [method TLSOptions.client] and [method TLSOptions.client_unsafe].
