A non well formed numeric value encountered - Wrong polygon data

[Okspen]

Hi. Thanks for the project!

The issue concerns PHP 7.1 and the "A non well formed numeric value encountered" notice.

It occurs here: offline-country-reverse-geocoder.php:80. $pointY appears to have a ) in the end.

Looks like the problem is in the wrong polygon data. It can be checked by looking for 41.871933000000126) in polygons.properties file.

I have solved the problem by trimming $pointX and $pointY.
$pointX = trim($pointX, '()');
$pointY = trim($pointY, '()');

Thanks
