Custom field for CMB2.

Adds the ability to add custom fields to the new WooCommerce HPOS orders page.

Follow the example in example-field-setup.php for a demonstration. The example assumes you have both CMB2 and this extension in your mu-plugins directory. If you're using CMB2 installed as a plugin, you can remove the require_once line.

You can retrieve the meta data using the following:

$test_text_value = wc_get_order( $order_id )->get_meta( 'yourprefix_woo_orders_text', true, 'edit' );
