Create support for B2BKing

Hi there,

We are using B2BKing and when installing your filter plugin, no ordres where shown for the subaccounts logged in. B2BKing did an adjustment to your plugin. Possible you can include it in future releases?

“`I guess the issue is that the query of the filter plugin is not searching parent account orders. I don’t know of any orders filter plugin that would be compatible.

I looked through the code of that plugin. In class-wos-public.php I made some changes to the function wos_woocommerce_my_account_my_orders_query() to modify that query.`”
