    Implement fast decimal integer encoding.
    
    Compared to 'blaze-textual' and the Integer 'Show' instance the 'integerDec'
    builder is 2x faster for small integers that fit into a machine word, and it
    is 4x faster for large integers. This performance improvement speeds-up the
    encoding performance of libraries like 'aeson' that use 'Integer's to
    represent numbers.
