PHP 8.4 deprecations - Implicitly marking parameter as nullable is deprecated

[campbell-m]

There are at least a couple of instances of this deprecation message:

Email\Parse::__construct(): Implicitly marking parameter $logger as nullable is deprecated, the explicit nullable type must be used instead
Email\Parse::__construct(): Implicitly marking parameter $options as nullable is deprecated, the explicit nullable type must be used instead

There may be more. I believe it should be fixable as the nullable type declaration is allowed from PHP 7.1.
