Fix Binder instance run
1 unresolved thread
1 unresolved thread
In MR !62 (merged); I broke the generation of Binder instance, as strangely enough the Conda environment that works on Linux and for Docker images utterly fail in Binder (and the version that works for Binder fails locally and for Linux images... 
Here I fix this, albeit not in the prettiest possible way (basically I provide two different Yaml environments: one for local/Docker and another for Binder.
I have updated the README to reflect both changes.
Note: I have in fact locally worked on top of the branch provided in !62 (merged) and have cherry-picked the commits to put them on top of current master branch.

Did you try C++ 17 standard in the notebooks? (see https://github.com/jupyter-xeus/xeus-cling/issues/461)
If it works well for you I'll give it a try; it would be better to avoid setting up two different environments...

In fact when trying again it wasn't even the C++ 17 issue that popped up, but the building of Anaconda environment on top of continuumio/miniconda3 image (see below)

I tried again building the
xeus-clingDocker image with gcc 10.4, and I got:➜ docker build -f docker/Dockerfile.xeus-cling -t xeus-cling:local .
