Major bootstrapping bug fixed

Major bug discovered in my implementation of bootstrapped tau using inds. I was previously indexing by i,j rather than inds[i],inds[j].

AVX2 vectorisation forced

Vectorisation on the CPU has now been forced. So if your CPU has AVX2 functionality (linux: sudo cat /proc/cpuinfo) then you should see a speedup. It gave me a ~47% speedup!

First release of tau statistic speedup
