Support converting to LaTeX

[Mohamed Abdelaal]

Hi all,

I'm using marko for a while and it is really a great lib.

I have a use case where I need to convert the parsed markdown into LaTeX format. I already did that by implementing a renderer for LaTeX.

Would it worse create a pull request for supporting LaTeX format as a build in functionality in marko?

Thanks a lot.
