Support for PHP 8.4

[CatoTH]

Hi! It would be great if your library would support PHP 8.4 (without deprecations). Here would be my suggestion:

• Use \Random\Randomizer::getRandom() instead of lcg_value (if available)
• Added nullability to parameters when appropriate
• Removed some null values if I couldn't find a nullable use (expect for from within test cases)
• Removed default parameters before mandatory parameters
• One unused import (unreleated)

I'll look into it, thanks!
