      This provides a native implementation of XOR codec by leveraging Intel ISA-L library function to achieve a better performance.

      Description

      Raw XOR coder is utilized in Reed-Solomon erasure coder in an optimization to recover only one erased block which is in most often case. It can also be used in HitchHiker coder. Therefore a native implementation of it would be deserved for performance gain.
