Dear Maintainer,

With this certificate config file:

  [main]
  certificate = /etc/ssl/lacme/main.pem
  certificate-chain = /etc/ssl/lacme/main-fullchain.pem
  certificate-key = /etc/ssl/lacme/main.key
  subject = /CN=host.domainA.example
  subjectAltName = DNS:*.domainB.example
  owner = root:ssl-cert
  notify = /usr/bin/systemctl reload nginx

And this command:

  lacme newOrder

lacme complains:

  [main] Warning: Ignoring invalid domain *.domainB.example

(Domain names changed for privacy.)

I am not sure what would need to happen to support wildcard certs, but I
would very much enjoy having that support.

Thanks,
-sam

P.S.: I am sorry that I am reporting from a somewhat old Ubuntu system. I
looked in your git repo and the same behavior seems to be present in the
latest version of lacme.
