Support for IPv6 in client_ip Field

[igor-kamil]

We encountered an exception when using the package due to the client_ip field not accepting IPv6 addresses. Below is the exception message:

Field client_ip (or IPC) has an unacceptable value '2a02:ab04:128:bb00:70c3:d04d:5f7e:e073'. Valid client IP address has to be a properly formatted IPv4. {"exception":"[object] (Chaching\\Exceptions\\InvalidOptionsException(code: 0): Field client_ip (or IPC) has an unacceptable value '2a02:ab04:128:bb00:70c3:d04d:5f7e:e073'. Valid client IP address has to be a properly formatted IPv4. at /data/e/b/ebbc5f46-1baa-403b-a381-ab942620ace1/dokumentmagazin.sk/private/vendor/backbone/chaching/src/Chaching/Drivers/TBCardPay/Request.php:201)

To ensure compatibility, it would be great if the package could handle IPv6 addresses for the client_ip field, either by allowing them directly or providing an alternative mechanism.

PHP version: 7.4
