LOC() rounds the seconds of latitude and longitude to two decimals, although a LOC record holds thousandths of a second of arc and RFC 1876 writes them up to 59.999.

D("foo.com", "none",
  LOC("a", 42, 21, 43.952, "N", 71, 5, 6.344, "W", -24.01, 1, 200, 10));

dnscontrol push stores 42 21 43.950 N 71 05 6.340 W -24.01m 1m 200m 10m instead of 42 21 43.952 N 71 05 6.344 W -24.01m 1m 200m 10m, about 6 cm off. When the provider already holds the precise record, dnscontrol preview proposes to replace it with the rounded one.

Cause: MakeLOC formats both seconds with %.2f before it parses the record. This came in with the dnsv2 refactor.

Fix: use %.3f for both seconds. The nine 045-loc golden records go back to the values they had before that refactor.

Test: the existing 045-loc.js case fails without the fix and passes with it. go test -p 1 -count=1 ./pkg/js/ ./models/ passes.

Thanks for fixing that!
