Internal Server Error / PHP 8

Hi,

WCFM is giving an Internal Server Error at checkout when on PHP 8.

Here’s the bug:

Uncaught TypeError: array_key_exists(): Argument #2 ($array) must be of type array,
Stripe\\Util\\CaseInsensitiveArray given in /......../plugins/wc-multivendor-marketplace/includes/Stripe/lib/ApiRequestor.php:402

Works with PHP 7.4
Fails with PHP 8.0

Please can you check. Thanks.
