Support for type 64 and 65?

[ImLunaHey]

I'm seeing requests with a type of UNKNOWN_64 and UNKNOWN_65.

These are SVCB and HTTPS (ref), PR welcome.

We have implemented support for the HTTPS record in the dns-packet fork we use for testing Firefox
https://searchfox.org/mozilla-central/source/testing/xpcshell/dns-packet/types.js#49
I'm not sure I'll have time to upstream the changes, but if anyone is interested I'm happy to help.
SVCB has the same wire format, so it should be easy enough to use the same implementation for both.

@mafintosh Could you please merge this? Or maybe you @valenting could make a PR?
