Support for other diagramming libraries [Enhancement]

[JohnLBevan]

Thank-you for creating this extension; it's awesome.

FYI: I use this extension when working with "markdown diagrams" in VSCode (also supports Atom): markdown-preview-enhanced. It would be great if this Chrome extension could support these various libraries too:

• mermaid.js (already covered)
• flowchart.js
• js-sequence-diagrams
• Plant UML
• WaveDrom
• vis
• vega / vega-lite
• ditaa

Obviously this goes well beyond the title / original scope of your extension, but I hope it's something you'd consider for the long term?
