Feature Request: Add support for post quantum encryption

CloudFlare released this blog post today: https://blog.cloudflare.com/post-quantum-crypto-should-be-free/

Turning on PQ safe crypto looks pretty easy:

If you use Tunnels with cloudflared then upgrading to PQC is super simple. Make sure you’re on at least version 2022.9.1 and simply run cloudflared --post-quantum.

Great suggestion, thanks a lot. I will have a look and see if there are any downsides (e.g. performance), since it is not really necessary right now if we are being honest ;-). Nevertheless, if there are none, I think we should implemented it as default.
