Added SSE4.1 and AVX2 implementations of FAST SGR.

The self-guided filter speed tests show that:
- The SSE4.1 implementation of FAST SGR is ~35% faster than the corresponding
  implementation of SGR;
- The AVX2 implementation of FAST SGR is ~28% faster than the corresponding
  implementation of SGR.
