Support LaTeX equations in reports

[Aonnghus]

🚀 Feature

Parse and render LaTeX in the reports.

Motivation

It can be useful to write LaTeX stuff in the reports like equations, etc.

Pitch

The user could write LaTeX code directly into the markdown code surrounding the equations with $ signs or creating a "math" codeblock.
How GitHub handles LaTeX

$e=mc^2$ => $e=mc^2$

```math
\mathcal{V} = \frac{4}{3} \pi r^3
```

$$\mathcal{V} = \frac{4}{3} \pi r^3$$

MathJax could do the job just fine.
