This one was built by studying the HPACK Huffman table (RFC7541 appendix B). It creates 5 small tables (4*512 bytes, 1*64 bytes) to map one byte at a time from the input stream based on the following observations : * rht_bit31_24[256] is indexed on bits 31..24 when < 0xfe * rht_bit24_17[256] is indexed on bits 24..17 when 31..24 >= 0xfe * rht_bit15_11_fe[32] is indexed on bits 15..11 when 24..17 == 0xfe * rht_bit15_8[256] is indexed on bits 15..8 when 24..17 == 0xff * rht_bit11_4[256] is indexed on bits 11..4 when 15..8 == 0xff * when 11..4 == 0xff, 3..2 provide the following mapping : * 00 => 0x0a, 01 => 0x0d, 10 => 0x16, 11 => EOS
