Selecting attribute groups in module settings

I have a few payment modules that I've created/modified (BTCPayServer, Stripe and PayPal).

In them I have added the ability to prevent the payment module from coming up if an option is selected or a product is set as "forbidden" for that payment module.

This works great for products with the stock 2.5.2 version of LiteCart as they're already included in the [b][i]public_html/includes/functions/func_form.inc.php[/i][/b] file

I have a [url=https://github.com/litecart/litecart/pull/313/files]PR[/url] to include options (attribute_groups) in this file also.

Thank you, I have accepted your pull request. :)

My pleasure, and thank you for taking the time to review it.
