Unexpected `use*` methods input is not handled

[faissaloux]

use Valorin\Random\Random;

$generator = Random::useLower(range('A', 'f'));

$string = $generator->string(
    $length = 10,
    $lower = true,
    $upper = false,
    $numbers = false,
    $symbols = false,
    $requireAll = false
);

This makes the Generator pass through all upperse, lowecase ans symbols in between.

It returns string(10) "[CZbEeDaIa"

While I am expecting to return only lowercases since it's the only active option.

PS: Same issue with all the methods when the input is not what expected.
