[FR] Show TOC of the file

[dmytrodubinin]

Please confirm

• I am running the latest version of this plugin

Description: It would be nice to implement the ability to see the structure (Table Of Content) of the file for quick navigation through it. For example in wiki.vim plugin we can generate wikitoc modal with file structure: The best option is two implementations: creating TOC directly to a file and as a pop-up window

I agree. Although there are already a few plugins for markdown editing that can do that.

That being said, this is something that could fit nicely with what @renerocksai had in mind in term of side panel. See discussion https://github.com/renerocksai/telekasten.nvim/discussions/23#discussioncomment-1754511

See #213 which is basically an extension of this idea.
