dev-python/nbdime: New package.

nbdime provides tools for diffing and merging of Jupyter Notebooks.
Beside console based diffing and merging tools, web-based diffing
and merging tools are provided (requiring npm).

The ebuild is based on the live ebuild in the science overlay,
https://github.com/gentoo-science/sci, which was added by me to
the overlay.

Gentoo-Bug: https://bugs.gentoo.org/604372

Package-Manager: portage-2.3.0
Closes: https://github.com/gentoo/gentoo/pull/3301
