Modern Huffman coders are using "Length-Limitted Huffman Codes"
For ex. when the length is limited to 12-15, you can store the length array
using only fixed nibble bitpacking combined with RLE (run length encoding) or ZLE (zero length encoding). Single table decoding is also simplified and very fast.
