Add binder config, drop pytest-tornado

[Carreau]

with slight modification to install nbdime.,

[krassowski]

I did not compile for me when tested on https://mybinder.org/v2/gh/Carreau/nbdime/binder?urlpath=tree

the compilation errors would be down to node setup issue?

Here is another template for reference: https://github.com/jupyterlab/extension-template/blob/main/template/%7B%25%20if%20has_binder%20%25%7Dbinder%7B%25%20endif%20%25%7D/postBuild.jinja

This seem to be doing about the same, except it's using a super complicated python script, instead of setting bash -x to each which commands are ran.

[krassowski]

Yeah, I am not opinionated on the language, whichever does the job.

[Carreau]

@vidartf you are a maintainer of pytest_tornado, it has not been released in 6 years but is incompatible with latest setuptools, should it still be used ?

[Carreau]

Ok, it should work now; I also drop pytest-tornado which is broken with latest setuptook and has not been released in 6 years.

[krassowski]

Thank you @Carreau!

[Carreau]

thanks for the review and merging
