2.6 removes python3-decorator dependency

There are a few dependencies listed in requirements/default.txt, the library can be imported without them, do you know if it's usable without them?

[pbui]

@paper42 Thanks for taking a look. I have removed the python3-decorator dependency.

The basics of networkx work without the other packages... meaning you can create a graph, add nodes, add edges, and run various algorithms on the structures. You will need the other packages to visualize those structures however and perhaps do some processing.

I would be fine with adding them as actual dependencies as that is what Arch Linux does:

https://archlinux.org/packages/community/any/python-networkx/

And it is what the upstream authors list as requirements.

Let me know how you think we should proceed.

I think we should leave it like this, thank you for looking into it.
