   Hello, I have some questions about the CodingLoop implementations you have written

   Such as ByteInputOutputTableCodingLoop and InputOutputByteTableCodingLoop. In the case of the former, it uses byteCount as the outer loop, leading to the creation and destruction of too many temporary variables, ultimately resulting in
   slower execution speed compared to the latter.
   However, for OutputInputByteTableCodingLoop and InputOutputByteTableCodingLoop, even though the number of variable creations and destructions is similar, isn't it supposed to be fewer in the former? Why is it that the latter runs faster instead?

   Here are my test results:

   • ByteInputOutputTableCodingLoop encodeParity: 163.9 MB/s
   • InputOutputByteTableCodingLoop encodeParity: 726.4 MB/s
   • OutputInputByteTableCodingLoop encodeParity: 477.1 MB/s

   I hope to get some clarification from you.
