HPACK Huffman encoding/decoding tables per RFC 7541 Appendix B. These tables are used internally by H2_hpack. Direct use is not recommended and the API may change without notice.
val encode_table : (int * int) array
encode_table.(i) returns (code, code_length_in_bits) for byte value i. Used by the Huffman encoder.
val decode_table : (int * bool * char) array
State machine table for Huffman decoding. Each entry is (next_state, is_accepting, output_char).
