EARTH_RADIUS is inconsistent

https://github.com/iitc-project/ingress-intel-total-conversion/blob/9708519e9089c76184e7eb62c77b331b7b52762a/main.js#L187 defines window.EARTH_RADIUS=6378137;

https://github.com/iitc-project/ingress-intel-total-conversion/commit/2bdc063a modifies Leaflet to use the same radius as S2 - 6367000

wackiness may ensue
