Remark plugin for turning HTML directive into MDX tags.
Turn:
---
blockBreak: true
---
::::div{.abc}
xyz
:::p
foo
---
bar
:::
::::Into:
<div class="abc">
xyz
<p>foo</p>
<p>bar</p>
</div>pageBreak 将 root 级别（容器指令外部）的 --- 分割线作为分页依据，
把每段内容包裹进 div{.<class>}（类名即 pageBreak 的取值，如 a4）。
---
pageBreak: a4
---
A
---
B转为：
<div class="a4">A</div>
<div class="a4">B</div>pageBreak 与 blockBreak 相互独立、可并存：
blockBreak: true作用于容器指令内部的---。pageBreak: <class>作用于 root 级别（容器外部）的---。
---
blockBreak: true
pageBreak: a4
---
:::div
A
---
B
::::
---
X:::div 内部按 blockBreak 拆成两个 div，root 级别的 --- 再按 pageBreak
将整体拆成两个 div.a4。
仅当文档中存在 root 级
---时才包裹，重复处理结果为幂等（分割线在首次处理即被消耗）。
Only some HTML tags are supported.
