Global provider for unique values.

This provider is used in AbstractFaker class implementations to control global unique generation configuration of faker providers.

Example usage:

val faker = Faker()
faker.unique.configuration {
    enable(faker::address) // enables unique generation for all functions of Address provider
    enable(faker::name) // enables unique generation for all functions of Name provider
    exclude(listOfValues) // exclude values from `listOfValue` collection from being generated (for all providers that are enabled for unique generation)
    enable(faker::internet) { enables unique generation for all functions of Internet provider
        exclude(listOfValues) // exclude values from `listOfValue` collection from being generated with Internet provider
        exclude(faker::internet, listOfPatterns)
    }
}
