Move & Update

The Problem

The package is severely out of date, and does not support PHP 8. Additionally, there is now the WP-OOP org that tackles WP-specific concerns.

Suggested Solution

• Move repo to wp-oop/events, including package rename, etc.
• Add support for PHP 8 (Add PHP 8 support #17).
• Update signatures (EventInterface's setter methods should return void #19).
• Remove deprecated, unused, and obsolete dependencies (Stop using deprecated dhii/i18n-helper-base package #18).
• Discontinue usage of dhii/psr-14 in favour of current psr/event-dispatcher and dhii/event-interface. The standard moved on, and so should we.
• Update the environment, tools, and configs to be in line with dhii/php-project.
