Huffman Encoder

The 4th module which is the Huffman encoder is required to produce the codes.  These codes have been precalculated and stored in two separate LUTs for DC and AC coefficients.  The runlength category pair serves as the address for AC LUT while DC LUT has only the category as its input address.  This module thus outputs the compressed codes which  will be packed by the data packer.
