-           Filter duplicate regex
-           Each regex is paired with a group number, so when removing a regex. The group number needs to be removed as well
-           The config file does not support map values or tuples, so they are stored as two separate arrays which is an absolute pain to get them working together
-           Normally to remove exact duplicates you can use Set<>, but since there are group numbers we can't use that as we need to know the index number in both arrays.
