newlines in custom textarea field

I was having problems with disappearing newlines in custom textarea fields. I solved it by modifying the code of your plugin as follows:

woocommerce-pdf-invoices-packingslips.php, line 246

echo $field_label . nl2br ($custom_field);

I think this is useful for everybody. Can you add this to the next version?
