Change "Shippping" to "Postage" on invoice.

Hello Greg,
You can do this by adding the following filter to your theme’s functions.php:

add_filter( 'wpo_wcpdf_woocommerce_totals', 'wpo_wcpdf_shipping_totals_label' );
function wpo_wcpdf_shipping_totals_label ( $totals ) {
	if ( isset($totals['shipping'])) {
		$totals['shipping']['label'] = 'Postage';
	};
	return $totals;
}

Hope that helps!

Thank you, that worked brilliantly.
