Consider adding markdown support for Readwise tag conventions

Hello,

I love the idea of this plugin. I have been using Readwise for years and one of my favourite features is chapter tagging in highlights. Essentially you highlight a chapter heading, add a note (.h1) and the heading is automatically recognised by RW as a chapter heading. They do the same for concatenating paragraphs, where you can use .c1, .c2 etc. to string different snippets together.

I will likely stay a RW user as they support Instapaper and other tools, but the conversion of chapter headings into markdown is an incredible timesaver & I suspect many might benefit.

Best wishes,
Flatlines
