Deprecated: Required parameter $refund_data follows optional parameter $bco_transaction_id

[DanielMarklund]

Hi! A minor issue that I'd prefer to be fixed, as it's clogging up error logs when logging depreciations.

Versions:
PHP: 8.0.0
Wordpress: 6.0.1
WooCommerce: 6.8.0
Billmate Order Management: 1.2.2

Error message:

( ! ) Deprecated: Required parameter $refund_data follows optional parameter $bco_transaction_id in *****/wp-content/plugins/billmate-order-management-for-woocommerce/classes/class-bom-api.php on line 65
