fallback to Spatie\Newsletter\Drivers\MailChimpDriver::class

[hebertlima]

I am creating a driver to use RD Station with this lib. However, even after changing the NEWSLETTER_DRIVER to my driver, MailChimpDriver is still being called.

Example:
'driver' => env('NEWSLETTER_DRIVER', App\Drivers\RDStationDriver::class),

I am using version 4.11, and I am still using PHP 7.4.

Ps. I plan to make this feature available once the integration is complete. RD Station is very popular in Brazil.

Edit:

Looking at the source code, it seems that the way to create new drivers was not present in the mentioned version, and it will be necessary to use the latest version for integration.
