[rich-text-plain-text-renderer] Allow custom render nodes to be provided like Rich Text Html Renderer

[localpcguy]

Feature Request: Allow custom render nodes to be provided like Rich Text Html Renderer. Use the same syntax as the RichTextHtmlRenderer does.

By allowing custom render nodes to be passed, users can handle things like embedded entries (see #161) as well as allowing for custom output for items such as links where both the text and uri would likely be desired.

An example:

A link could look something like this:

const customTextRenderNode = {
  renderNode: {
    [INLINES.HYPERLINK]: (node, next) => `${next(node.content)}: ${node.data.uri}\n`,
  },
};

And be called like this:

const renderedText = documentToPlainTextString(richTextDocument, null, customTextRenderNode);

Hey @localpcguy , that sounds like a good idea. Is that something you are willing to submit a PR for?

Sure, I can take a stab at it
