I have a file test.rst that has custom RST directives.
This is generated from a sphinx-build documentation.

The main title
==============

Some paragraph content.

.. myproject:component:: /path/to/my/component

 Description of my component.

Testing with pandoc --verbose -t native test.rst

The output is:

[Header 1 ("the-main-title",[],[]) [Str "The",Space,Str "main",Space,Str "title"]
,Para [Str "Some",Space,Str "paragraph",Space,Str "content."]]

As you can see the custom directive is not present in the AST.

I was looking at the RST Reader: https://github.com/jgm/pandoc/blob/master/src/Text/Pandoc/Readers/RST.hs#L1520

What is a good way of adding a new directive to Pandoc so that when I convert the RST file to Markdown it can get interpreted.

First I need the Reader to understand those custom directives.

Please advise.

Thank you!
