Noetic support

[InigoMoreno]

I have a working version of smach_viewer in noetic!

I have refactored a lot of the code (especially on the xdot library), so it might be a bit difficult to read through the changes.

The rosdeps are not correctly defined, as not all of them are available (I will need to do a PR of ros_distro). To run the repo you need to install the following manually (not sure which are necessary):

 apt install gir1.2-gtk-3.0 python3-gi python3-gi-cairo python3-numpy graphviz
 python3 -m pip install xdot wxpython

Also, I can't create a new branch on the repo, so I set the base of the fork to melodic-devel, but Ideally, a new noetic-devel branch should be created and the base of this fork changed.

Fixes #29
Fixes #34
Fixes #36

I have been looking into the deps and I believe only these two are missing from the rosdeps:

apt install python3-gi-cairo
 python3 -m pip install xdot

Did you request them to be added there?

Xdot got merged. Can somebody trigger CI again?

[Timple]

Seems like kinetic should be removed from CI

In addition, from here I needed the following:

sudo apt install libxt-dev libgirepository1.0-dev

pip install pycairo PyGObject

Since the melodic branch has changes inspired by this PR to fix noetic, can this PR now be closed?

Because it has major conflicts and it suggests that noetic is not supported 🙂

Agreeing with @Timple to close this PR.
