I've added SSE2 and isn't faster (bleeding-jumbo)

pomelo documentation says:
"In POMELO, function H makes the attack using SIMD expensive
since the function H uses password-dependent memory accesses."

I've added also tunable costs for pomelo_fmt_plug.c

I don't know what to do with avx2 because

[a@...er src]$ ./configure | grep -i avx
checking for AVX... yes
checking for AVX2... no

thanks
