https for www-server.co.uk with automatically-generated letsencrypt certificates

I would like AAISP to follow in the footsteps of Mythic-Beasts, and support HTTPS on the www-server.co.uk machine.
This can simply autogenerate certificates via LetsEncrypt and rely upon TLS-SNI to use a single IP address to host all the sites.

The scripting doing this would need to check if the AAAA/A/CNAME pointer actually points to the www-server before actually updating certificate etc but I wouldn't see this as a problem.

HTTPS support is also important as part of generally encouraging encryption with customers etc. of course!.
