RepeatingGroupFix unorder

[lucas-magalhaes-BTG]

Could you add the option to validate or not the order of the tags in the Repeating Group? Today it is only possible in the message as a whole, but when you use it it throws the following error: "Repeating group fields out of order (group 146: template is wrong or delimiter 55 not found: expected 7596 groups, but found 1)".
