Ability to split cells to individual files (code & markdown)

First, I find jupytext very useful in its current state. I add this as an issue, although it may be more akin to a feature, open to discussion.

I usually have very large Jupyter Notebooks. I keep them in version control (git) as synced markdown files. However, those md files tend to be pretty long, which is typical against good git+code practices. To me, it seems natural to think that jupytext should be able to support converting a notebook, based on cells, to individual *.py and *.md files. These files could maintain ordering by their filename, e.g. 01_introduction.md, 02_sample_query.py, 03_eval.md etc.

Is there a reason that this is not yet considered in jupytext?

Hi @Sieboldianus , well, may I encourage you to try implementing this format? The fact that you plan to write to a directory makes it a bit different from jupytext.read and jupytext.write, so maybe you should implement that format in another python package, and if it works well then later on we can see how to extend Jupytext with that format?

Thank you @Sieboldianus . Yes indeed, I agree, supporting notebooks as many files looks challenging. Thank you for keeping us posted about the results of your attempts!
