6.5.5 introduced a breaking change, minor feature request

[rr-anthony-prato]

This was unexpected on a minor version. From the change log:

Updated the method onTokenRegistrationFailed(_ reason: String?) to onAuthFailure(_ authFailure: AuthFailure). The new AuthFailure object provides more detailed information about JWT failures.

The fix is easy however the new AuthFailureReason enum is Int-backed so to aid in logging it would be helpful if this enum conformed to CustomDebugStringConvertible
