[Feature suggestion] About identify $\ce{}$ in a formula

[boxie123]

Describe your feature request

The \ce{} provides a lot of conveniences when I type some chemical language. It can convert some characters to superscripts and subscripts automatically.

For example, $\ce{CO2 ->[\Delta] C + O2 ^}$ will obtain the same result as $CO_2 \xrightarrow{\Delta} C + O_2\uparrow$ .

Typora and Zettlr both support the function. However, Mark Text doesn't.

Thank you very much if you can add this function.

What problem does this feature solve? [optional]

There are a large number of people in the world engaged in chemistry-related work. Adding this feature will make it more convenient for us to edit markdown documents through Mark Text!

描述您的功能请求

当我输入一些化学语言时，\ce{} 提供了很多便利。 它可以自动将某些字符转换为化学符号或者上下标。

例如，$\ce{CO2 ->[\Delta] C + O2 ^}$ 将获得与 $CO_2 \xrightarrow{\Delta} C + O_2\uparrow$ 相同的结果。

Typora 和 Zettlr 都支持该功能。 但遗憾的是，Mark Text 没有。

如果可以添加这个功能，非常感谢。

这个功能解决了什么问题？ [可选的]

世界上有庞大的人数在从事与化学有关的工作。 增加这个功能会让我们使用Mark Text编辑markdown文档更加方便！

KaTex supports \ce via mhchem extension. However MarkText doesn't seem to include it.

There's also a PR (#2327 ) linked to this issue.
