/**
 * OrderedTimeCodec encodes and decodes a UUID, optimizing the byte order for
 * more efficient storage
 *
 * For binary representations of version 1 UUID, this codec may be used to
 * reorganize the time fields, making the UUID closer to sequential when storing
 * the bytes. According to Percona, this optimization can improve database
 * INSERTs and SELECTs using the UUID column as a key.
 *
 * The string representation of the UUID will remain unchanged. Only the binary
 * representation is reordered.
 *
 * **PLEASE NOTE:** Binary representations of UUIDs encoded with this codec must
 * be decoded with this codec. Decoding using another codec can result in
 * malformed UUIDs.
