No attachment meta data

As a dev I found myself needing the height and width of an attachment. This plugin doesn’t fill in fields that wp_get_attachment_metadata() should return. A function to get the height and width of an svg file might look something like the code below. Please consider adding this feature to your already amazing plugin.

function find_svg_dimensions( $svgUrl ) {

	$svgString = file_get_contents($svgUrl);
	$svgElement = simplexml_load_string($svgString);

	// do a return check here to see if height and width even exist
	// if (check) return false;

	$height = intval($svgElement['height']);
	$width = intval($svgElement['width']);

	if ( ! isset($height) || ! isset($width) ) {
		$viewBox = 	explode(' ', $svgElement['viewBox']);
		
		// check if $viewBox is set
		if ( ! isset($viewBox) ) return false;

		// https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/viewBox
		$minX = intval($viewBox[0]);
		$minY = intval($viewBox[1]);
		$width = intval($viewBox[2]);
		$height = intval($viewBox[3]);

		$width = $width - $minX;
		$height = $height - $minY;
	}

	return array(
		"height" => $height,
		"width"  => $width
	);
}

I didn’t fully test this code, so take it with a grain of salt.

THANKS!
