geosimplify-js polyline simplification library

Based on https://github.com/mourner/simplify-js, geosimplify-js fixes the problem that the simple pythagorean measure used in simplify-js changes size if you simply give it longitude/latitude sequences to simplify.

Used in the QML plugin of Qt Location.

The sources can be found in tqtc-qt5/qtlocation/src/3rdparty/geosimplify.js.
