Set up Mayavi on Binder

I've create a [plotting module for SymPy](https://github.com/Davide-sd/sympy-plot-backends) which is also using Mayavi. I'd like for the users to be able to try the module without installing it, so I set up Binder. Unfortunately, I'm not able to load it: every time I get an error, and I've raised the white flag. Right now, the Binder is working without Mayavi :|

The first time I tried the error told me it was missing `libgl.so.1`. I added the requirement for `libgl1-mesa-glx` and that fixed it.

Next, I got an error about `libxcb`: so I looked over my system with `apt-cache search libxcb` and found the following list:
```libxcb-composite0 libxcb-composite0-dev libxcb-damage0 libxcb-damage0-dev libxcb-doc libxcb-dpms0 libxcb-dpms0-dev libxcb-dri2-0 libxcb-dri2-0-dev libxcb-dri3-0 libxcb-dri3-dev libxcb-ewmh-dev files libxcb-ewmh2 libxcb-glx0 libxcb-glx0-dev libxcb-icccm4 libxcb-icccm4-dev libxcb-image0 libxcb-image0-dev libxcb-keysyms1 libxcb-keysyms1-dev libxcb-present-dev libxcb-present0 libxcb-randr0 libxcb-randr0-dev libxcb-record0 libxcb-record0-dev libxcb-render-util0 libxcb-render-util0-dev libxcb-render0 libxcb-render0-dev libxcb-res0 libxcb-res0-dev libxcb-screensaver0 libxcb-screensaver0-dev libxcb-shape0 libxcb-shape0-dev libxcb-shm0 libxcb-shm0-dev libxcb-sync-dev libxcb-sync1 libxcb-util-dev libxcb-util0-dev libxcb-util1 libxcb-xf86dri0 libxcb-xf86dri0-dev libxcb-xfixes0 libxcb-xfixes0-dev libxcb-xinerama0 libxcb-xinerama0-dev libxcb-xinput-dev libxcb-xinput0 libxcb-xkb-dev libxcb-xkb1 libxcb-xtest0 libxcb-xtest0-dev libxcb-xv0 libxcb-xv0-dev libxcb-xvmc0 libxcb-xvmc0-dev libxcb1 libxcb1-dev libx11-xcb-perl libxcb-cursor-dev libxcb-cursor0 libxcb-imdkit-dev libxcb-imdkit0 libxcb-xrm-dev libxcb-xrm0```

Copied it into the requirement, a new error about `libxcb-imdkit` could not be found. Removed `libxcb-imdkit-dev libxcb-imdkit0`, the same old error about `libxcb`.

I think you got the picture. I have no idea how to set up Mayavi on Binder, if it's even possible.
