Separat sorting for enum cases

[m-lotze]

Feature request

It would be nice to be able to define a different sorting algorithm for enum cases or disable enum case alphabetic sorting when using this configuration

'ordered_class_elements' => ['sort_algorithm' => 'alpha', 'order' => ['use_trait', 'case', 'constant_public', 'constant_protected', 'constant_private', 'property_public_static', 'property_protected_static', ...]],

the order of declaration might be important for an enum, since Enum::cases() returns it in this order.
