      public ByteBuffer compress(ByteBuffer inBuffer, RangeParams rangeParams)
      Compress data using the CRAM 3.1 arithmetic (range) codec with the given parameters. The input buffer is consumed (position advanced to limit) and the returned buffer is rewound.
      Parameters:
      inBuffer - input data to compress (position to limit is compressed)
      rangeParams - encoding parameters controlling order, RLE, PACK, STRIPE, and other flags
      Returns:
      a rewound ByteBuffer containing the compressed data
