v2.0.0-RC1

v2.0.0 introduces several major changes for ZDNS.

Highlights include:

• The largest change was a refactor to split ZDNS into a core library and a CLI wrapper that utilizes the library. With this change, other Go tools will be able to interface directly with ZDNS without having to call and parse CLI output.
• Support for DoH and DoT lookups
• Proper --all-nameservers support that queries every nameserver at each step of the iteration process
• CNAME/DNAME following for all lookups by default
• --validate-dnssec adds support for a full validation of DNSSEC for a given record (thanks to @developStorm for this feature!)

Along with a host of bug fixes, performance improvements, testing enhancements, and smaller features.
