Show HN: Jupytext.nvim

I wrote this plugin for Neovim to be able to edit Jupyter notebook .ipynb files directly in Neovim. The native format for notebooks is quasi-binary json. This plugin uses the jupytext tool (https://github.com/mwouts/jupytext) to convert that json to a plain text representation (markdown or code) on the fly, and back to json when the file is saved.
