Support for 3.x

[peteraba]

Hey!

Thought I'd ask this project going to support the 3.0 branch of php-casbin or will it be deprecated?

Thanks!

@basakest can you update this repo to PHP-Casbin 3.0 ?

@peteraba released v1.3.0: https://github.com/php-casbin/database-adapter/releases/tag/v1.3.0

that was fast, thank you @hsluoy, @techoner !
