Update PSR-3 version? #35
Description
I've been using a plugin that makes use of this mailer in DokuWiki, and my code is currently using PSR-3 version 3 which has type hinting on the LoggerInterface. While I can fix the immediate issue by downgrading to version 1 for now, is there any appetite for updating this mailer to use at least version 2 of the logging PSR?
The upgrade process is described here: https://www.php-fig.org/blog/2019/10/upgrading-psr-interfaces/
