      public SimpleChunk​(byte[] data, long offset, byte[] hash)
      Creates a new simple chunk.

      The getHexHash() is cached and will be generated upon construction based on the given hash.

      Parameters:
      data - The data contained in this chunk, not null and not empty
      offset - The offset of this chunk, with respect to its source data stream, must be positive
      hash - A binary hash representation of the contained data. Using the algorithm specified during construction by the Chunker. Not null and not empty.
