Add LOC record conversion into human-readable values

[phillip-stephens]

Currently we're just returning the raw DNS values for LOC record types.
Let's add parsing into human-readable values.
This would resolve the TODO here.

RFC explaining the LOC record
I've setup a LOC record @ loc.prstephens.com

dig gives nicely formatted output

$ dig -t LOC loc.prstephens.com

; <<>> DiG 9.10.6 <<>> -t LOC loc.prstephens.com

ZDNS does not.

$ ./zdns LOC loc.prstephens.com
00h:00m:01s; 0 names scanned; 0.00 names/sec; NaN% success rate;
{"name":"loc.prstephens.com","results":{"LOC":{"data":{"additionals":[{"flags":"","type":"EDNS0","udpsize":1232,"version":0}],"answers":[{"altitude":10003000,"class":"IN","horizontal_pre":18,"latitude":2282209648,"longitude":1707686648,"name":"loc.prstephens.com","size":18,"ttl":280,"type":"LOC","version":0,"vertical_pre":18}],"protocol":"udp","resolver":"171.64.1.234:53"},"duration":1.422555166,"status":"NOERROR","timestamp":"2025-04-10T10:03:11-07:00"}}}
00h:00m:01s; Scan Complete; 1 names scanned; 0.70 names/sec; 100.0% success rate; NOERROR: 1

Let's get the output to contain formatted output similar to dig with JSON keys matching what the RFC states.

Todos

• Add a conversion function for taking raw LOC values -> Formatted GPS coords. Code pointer to the LOC object parsing
• Add a unit test to check your function. Ex. of unit tests here
• Open a PR and list the changes and what testing you've done
