 @brief Enrolls a UnionPay card and returns an enrollment ID. The `enrollmentID` property of `BTCardRequest` must be set to this IDbefore the card can be tokenized.

 @discussion Attempting to enroll cards that do not require enrollment -- including non-UnionPay cards -- will cause an error. This
 can be prevented by checking the card's capabilities first.

 @param request A card tokenization request that contains a card, mobile phone number, and country code. Cannot be `nil`.
 @param completion A callback block that will be invoked on the main thread when enrollment has completed. When enrollment succeeds, `error` is `nil`, `enrollmentID` contains the enrollment ID, and `smsCodeRequired` indicates whether an SMS code was sent to the customer. If an SMS code is not sent, tokenization can occur immediately afterwards.
