Feature request: preview mermaid in markdown

[Sonya-c]

Other markdown editor like typora have support for mermaid diagrms. It could be amazing if panwriter could render mermaid

Thanks for the idea! Currently, I'm mostly trying to have the PanWriter preview be on feature-parity with pandoc itself, and pandoc doesn't support mermaid out of the box. But maybe I sould start thinking about an extension system to PanWriter so that people can customize it to their liking...

Perhaps https://github.com/raghur/mermaid-filter could solve the issue? Haven’t tried it yet.
