/**
 * TimestampLastCombCodec encodes and decodes COMBs, with the timestamp as the
 * last 48 bits
 *
 * The CombGenerator when used with the StringCodec (and, by proxy, the
 * TimestampLastCombCodec) adds the timestamp to the last 48 bits of the COMB.
 * The TimestampLastCombCodec is provided for the sake of consistency. In
 * practice, it is identical to the standard StringCodec but, it may be used
 * with the CombGenerator for additional context when reading code.
 *
 * Consider the following code. By default, the codec used by UuidFactory is the
 * StringCodec, but here, we explicitly set the TimestampLastCombCodec. It is
 * redundant, but it is clear that we intend this COMB to be generated with the
 * timestamp appearing at the end.
 *
 * ``` php
 * $factory = new UuidFactory();
 *
 * $factory->setCodec(new TimestampLastCombCodec($factory->getUuidBuilder()));
 *
 * $factory->setRandomGenerator(new CombGenerator(
 *     $factory->getRandomGenerator(),
 *     $factory->getNumberConverter()
 * ));
 *
 * $timestampLastComb = $factory->uuid4();
 * ```
