ReferralRejectionReason.ReasonEnum doesn't include ReferralCustomerAlreadyReferred

[natalie-zamani]

We use the following to parse the rejectionReason from a referral error:

ReferralRejectionReason.ReasonEnum.fromValue(props.rejectionReason)

But ReferralRejectionReason.ReasonEnum doesn't include an enum for ReferralCustomerAlreadyReferred, which is defined in your documentation and is being sent back to us by the API in certain cases. This is causing the following exception:

java.lang.IllegalArgumentException: Unexpected value 'ReferralCustomerAlreadyReferred'
	at one.talon.model.ReferralRejectionReason$ReasonEnum.fromValue(ReferralRejectionReason.java:89)

Could you please add that enum value, and any others that may be missing from your library?
