Implement 'raw/endraw' statement

[flexferrum]

Implement 'raw/endraw' statement according to Jinja2 documentation:

For bigger sections, it makes sense to mark a block raw. For example, to include example Jinja syntax in a template, you can use this snippet:

{% raw %}
    <ul>
    {% for item in seq %}
        <li>{{ item }}</li>
    {% endfor %}
    </ul>
{% endraw %}

I. e. everything between raw/endraw tags should be copied to the destination string as-is, without any interpretation.

Which would be the best approach?
Handle them as a Statement? or create a new regex for them and handle them at their own way in ParseRoughMatch?

I'm considering the second option. I. e. do it in ParseRoughMatch, similar to comments handling.

Ok, I will try that. I think that is the way it is implemented in the python version
