> Refactor `AdapterFingerPrint` to remove the notion of compact representation. As the memory for storing fingerprint is always allocated next to the `AdapterFingerPrint` object, use of `_value` array is not required. This simplifies the implementation a bit, and would also fix the "false" positives flagged by ubsan when accessing `_value` array beyond its size (See the description in JBS issue).
