Install numpy before bx-python in case you are installing from sdists #4982

bx-python does not explicitly require numpy because it's only used to enable extra features, however, Galaxy depends on those extra features. This isn't usually a big deal because the bx-python wheel is built with numpy, but if you were to build the dependencies from source (explicitly with pip install --no-binaries :all: or pip install on a platform we don't build wheels for) using the requirements file, bx-python builds without numpy support and Galaxy fails to start:

  File "/home/nate/work/galaxy/lib/galaxy/visualization/data_providers/", line 14, in <module>
    from bx.bbi.bigbed_file import BigBedFile
ImportError: No module named bigbed_file

Installing numpy before bx-python fixes this.

Can you also please document this in a short comment, so we don't regress in the future?
