GM-Standards SM2/SM3/SM4/SM9/ZUC for Go

This is a SM2 sm2p256v1 implementation whose performance is similar like golang native NIST P256 under amd64 and arm64, for implementation detail, please refer SM2实现细节.

This is also a SM3 implementation whose performance is similar like golang native SHA 256 with SIMD under amd64, for implementation detail, please refer SM3性能优化.

For SM4 implementation, SIMD & AES-NI are used under amd64 and arm64, for detail please refer SM4性能优化, support CBC/CFB/OFB/CTR/GCM/CCM/XTS modes.

For SM9 implementation, please reference sm9/bn256 README.md.

For ZUC implementation, SIMD, AES-NI and CLMUL are used under amd64 and arm64, for detail please refer Efficient Software Implementations of ZUC
