request for supporting ReST filter

[arcturusannamalai]

ReST mode is useful to write documentation for Python code as well as books for technical subjects in their own regard; see: https://docutils.sourceforge.io/docs/user/rst/quickstart.html

Specifically, the spell mode for ReST could skip over,

• code sections
• standard meta information / keywords in ReST
• etc.

I agree that a ReST filter will be useful. The existing markdown filter would be a good place to start.
