MQTT-SN Gateway that supports DTLS 1.3

[embhorn]

Per @fj-blanco -

right now wolfSSL seems like the only way to go for DTLS 1.3 (interesting for PQ for example). But wolfSSL's MQTT-SN is just the client, right? As far as I know, there's no Gateway/RSBM/broker that works with wolfSSL for DTLS, so setting up MQTT-SN communication over DTLS 1.3 doesn't seem straightforward. That's why I think DTLS support in wolfMQTT would be interesting.

As an update to this, I've created a fork adding DTLS 1.3 support to the Paho MQTT-SN Gateway via wolfSSL. I'm testing with the Paho GatewayTester publisher and subscriber clients, so it is not tested with the wolfSSL's MQTT-SN client yet.
