[bug] wrong sign causing divergence in javascript

[wohenbushuang]

eviltransform/javascript/transform.js

Lines 90 to 91 in b911c06

	newLat -= gcjLat - tmp.lat;
	newLng -= gcjLng - tmp.lng;

@Artoria2e5

wrong sign -=, it will cause divergence!

Yeah, I fixed that years ago in #42. It never got merged though.
