Encoder/decoder for google's JSON DNS message format based on libdns.
The API consists of a QueryEncoderFactory that creates QueryEncoder objects, that can encode libdns Message objects to a query string that can be used both with google's and cloudflare's DNS-over-HTTPS APIs (for cloudflare, using directly UDP wireformat with libdns's Encoder is recommended).
The JsonDecoderFactory creates JsonDecoder objects, that accept JSON strings and decode them back to Message objects.
