disabling specialUseDomains not working

[mapl]

When setting rfc6762-appendixG to false, special domains are still blocked.

specialUseDomains:
  rfc6762-appendixG: false

Is this to be expected?

I want to forward ANY DNS Query to the Upstream DNS Server.

rfc6762-appendixG only controls some of the special domain names. I guess we can add a enable option so the whole blocking can be fully opted-out of.
That option doesn't exist ATM because the RFCs say it's mandatory to block those TLDs. I guess if you have another internal DNS upstream of Blocky, and it blocks them, it's a valid use case.

Thanks, I created a PR for this #1614
