Pin emperor install at 0.9.51
Pin emperor install at 0.9.51

Emperor is required by qiime with version reqs:

emperor<1.0.0,>=0.9.51

It turns out that the current version, 0.9.60 has a broken install, giving this
error on /modern/ pip:

    error in emperor setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers; Unordered types are not allowed

What's weird is that this apparently worked at some point with the historical install on Legion.  I guess something changed in pip/setuptools.
