Cannot construct Point. x and y should be numeric: trim coordinates

[jbogdani]

Hello and thank you for this library.

I'm having an issue on loading WKT with extra spaces, for instance:

$geo = \geoPHP::load('POINT ( 1 1 )', 'wkt');

As I can see at Point.class.php the basic validation is failing due to the trailing space on the first coordinate. I know I can clean my data by removing these spaces, but the point is that POINT ( 1 1 ) is valid WKT, and I guess geoPHP should parse it correctly.

I guess that trimming the input could solve this issue:
Point.class.php:

if (!is_numeric(trim($x)) || !is_numeric(trim($y))) {
    throw new Exception("Cannot construct Point. x and y should be numeric");
}
// Check to see if this is a 3D point
if ($z !== NULL) {
    if (!is_numeric(trim($z))) {
        throw new Exception("Cannot construct Point. z should be numeric");
    }
    $this->dimension = 3;
}

The floatval below also trims the values, so there is no need to repeat the trim after the validation.

This has already been solved in several fork, for example look at mine.

Thank you @BathoryPeter! I guess the main repository is not actively maintained. I'm going to point at yours, thank you.
