Describe the feature

First of all, thank you to markdown enhance for providing powerful functionality support to vuepress markdown! However, it must be said that this plugin has now become very large and cumbersome, making maintenance increasingly difficult. Perhaps it is time to consider splitting it up.

My suggestion is to consider splitting from various perspectives such as new syntax, grammar extensions, third-party dependencies, resource embedding, and content container types.

For example, these combinations can be used as individual plugins.：

• content container: hint, github alerts, [code-group];
• new syntax: sup, sub, task list, footnote, mark, spoiler，include;
• grammar extensions: attrs, imgSize, imgMark, obsidianImgSize, imgLazyload;
• markdown render: breaks, linkify, figure, stylize;
• math Tex: katex, mathjax (optional deps);
• chart: chart, echarts, flowchart, markmap, mermaid, plantuml (optional deps);
• code blocks: [code-group], code-demo;
• code playground: kotlin-playground, vue-repl, typescript-playground
• ...more

I actually prefer function spliting, e,g. I will split imgMark imgSize and figure into one plugin called plugin-markdown-img.

Here are my plans:

• plugin-img: imgMark -> mark imgSize -> size figure -> figure
• plugin-math: katex or mathjax
• plugin-gfm:

Comparing the more complex aspects of splitting is challenging, especially with elements like sup, sub, task list, footnote, mark, spoiler, include, imgSize, imgMark, obsidianImgSize, imgLazyload, breaks, linkify, figure, and stylize. Distinguishing their categories can be quite tricky.

Considering these functions are relatively simple and independent, perhaps they can be separately implemented in the upstream mdit-plugins, then integrated into plugin-md-enhance. Meanwhile, plugin-md-enhance should only retain these functions, with others being separated out.

e.g:

• plugin-md-enhance: sup, sub, task list, footnote, mark, spoiler, include, imgSize, imgMark, obsidianImgSize, imgLazyload, breaks, linkify, figure, stylize
• plugin-hint: hint, github alerts
• plugin-math: katex or mathjax
• plugin-chart: chart
• plugin-echarts: echarts
• plugin-mermaid: mermaid
