   A wrapper around the attrTuple (key) and value pair seen in many formats.

   Includes the attrTuple-type explicitly, rather than embedding the corresponding information in the type of 'value', because otherwise it'd be difficult to extract the correct type for Byte and NumericSequence values.

   This class is roughly analogous to htsjdk's SAMTagAndValue.
