Incompatibility with WP-Rocket due to different monolog versions

[schakko]

NADI does can not be enabled if WP-Rocket is already activated. This comes because we are using an older interface definition of PSR-4/Log.

protected function write(array $record) {

has to be changed to

protected function write(array $record): void {

With upgrading to WP-Rocket 2.8.0, each reference to Logger::warn has to be replaced with Logger::warning.

The issue has been mentioned at https://wordpress.org/support/topic/problem-with-wp-rocket-9/.

Due to some dependencies, PHP 8.0 is required (#170).
