Error : conflict between latex and nunjucks

[laBecasse]

Hi again,
there is a error on the following post:

---
title: Hello World
---

$$\mathbb{{{x}}}$$

This multiple brackets can be include naturally by the use of latex macros with \newcommand allowed by pandoc.

The error is due to nunjucks considering the brackets template tags:

I propose to disable (or add an option to disable) nunjucks with hexo-renderer-pandoc. There are several known issues with nunjucks. And there is a way to disable it.

We can do it this way : https://github.com/laBecasse/hexo-renderer-pandoc/blob/511e19a162a907f103304e5d0e50aa238ebc70d4/index.js#L95

Sounds reasonable. I will update it.
