 Decoding a code word works by walking on the tree from the root to the children, matching each passed 0 or 1 to the next read input bit in RB in LSB to MSB order. When `t[i]` is set, then a valid code word was read and `i` is written to the next byte of output in RT in LSB to MSB order. When no set `t[i]` is encountered, and there are still input bits left, then the code word is >6-bits, so SO/OV/OV32 are set, and decoding stops.
