support of markup of orgmode as an input format

[nbehrnd]

I would like to propose an additional input format for sphinx, namely the markup of orgmode - either natively, or via an extension to Sphinx.

Similar to rst and Markdown, orgmode is a lightweight markup language. Karl Voit extends this to call the markup orgdown when recapitulating its syntax which -- different to the many dialects of Markdown -- only knows one orgmode syntax. Provided in Emacs and shipped in Emacs as one of the major modes, it is supported (natively / by an extension) by multiple tools today, i.e. no longer restricted to Emacs.

Thus I thought, if there is myst-parser to use Markdown files in Sphinx without prior (manual/pandoc) conversion, could there be a org-parser (tentative name) -- or is already one I missed to see?
