Update gonum.org/v1/gonum v0.7.0 to 0.9.0

[pravi]

We are packaging this module for Debian, but we already have gonum.org/v1/gonum v0.9.0 and would like to use that instead of 0.7.0

But one test is failing with the new version, so please update the test with new version.

From the log - it seems that the test in question is simply comparing the hash with the gold wmh.bin output.
I guess only @vmarkovtsev knows how this file was created in the first place in 1972482 but my guess is that it was done in Python.

If that is so - why changing the version of gonum changes the behaviour of gonum/stat/distuv (the only thing that seems to used from it in wmh.go) - is beyond me.

From a quick glance, there seems to be some changes in stat/distuv at https://github.com/gonum/gonum/releases/tag/v0.8.1 https://github.com/gonum/gonum/releases/tag/v0.8.1 but why should that affect the .Rand() \w a fixed seed (the only thing that is consumed in wmh.go) is a mistery 🤷
