    Add numpy to extras

    Move numpy out of requirements into extras, as it's not required
    for running browbeat, but only used for insights like compare
    results.

    So to install with insights, pip install .[insights], to perform
    the CLI operations such as compare.

    Added a tox test to ensure no dep conflict arises.
