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.
