``crc32_non_reflected(Polynomial,Initial,FinalXor,AppendLength)``
=================================================================

* ``Polynomial`` - Canonical non-reflected CRC-32 polynomial.
* ``Initial`` - Initial CRC accumulator value.
* ``FinalXor`` - Final xor value.
* ``AppendLength`` - Boolean flag controlling whether the message length is appended as little-endian bytes.


Parametric non-reflected CRC-32 hash function using a canonical polynomial, configurable initial value and final xor value, and optional appended little-endian length bytes.
