[feat] add magic method __call to call custom method of driver

[alissn]

Hi,

This pull request adds the magic method __call to Shetabit\Multipay\Payment to enable the calling of custom methods of drivers.

I think it solves issue #179. This enhancement allows us to add other custom methods to other drivers.

Usage example:

$payment = Payment::via('digipay')
    ->detail([
        'type'          => 13,
        'providerId'    => '855443ff-418f-44ad-8fbf-a7a5c1ffd0c9',
        'trackingCode'  => '4405940631710064990882',
        'invoiceNumber' => '12121',
        'deliveryDate'  => '2024-03-01',
        'products'      => [
            'test',
        ],
    ]);

dd($payment->deliver());

deliver is a public method of the Digipay gateway.

If further description or clarification is needed, please let me know.

the __call ruines the driver interface: https://github.com/shetabit/multipay/blob/master/src/Contracts/DriverInterface.php , then the consumer of driver will be coupled with the driver itself! the purpose of defining DriverInterface is decoupling from driver implementations.

if a method has not been defined in the interface, it should not be exposed even through __call magic method.
