dependencies listed multiple times

[nschloe]

If a dependency is listed more than once in install_requires or extra_requires (which is perfectly possible), e.g.,

    install_requires=["numpy"],
    extras_require={
        "all": ["netCDF4", "h5py", "lxml"],
        "exodus": ["netCDF4"],
        "hdf5": ["h5py"],
        "xml": ["lxml"],
    },

then it is listed multiple times in the web interface too, where it makes less sense:

Perhaps this can be uniqued.

Perhaps optional (extra) dependencies could be listed as such in the web interface, too.
