Add support for Latex to flutter_markdown_plus #15
Description
A lot of the other plugins for Markdown rendering support the rendering of Latex. This allows for e.g. maths formulas. Latex was never added to flutter_markdown but it has a plugin system, and there is already a decent and well-tested plugin. This is put together by an edtech firm in Germany and looks good, well-tested.

If you pull the latest code you'll see that I tried updating the test app and including the package but it was having none of it. Please investigate whether it's possible to override flutter_markdown as a dependency to flutter_markdown_plus (same as you can to force dependencies to a particular version. It would be nice if this worked.
If this is not possible then the best thing to do (and the most convenient for the German developer if they want to use their package with our plugin) is to fork flutter_markdown_latex and make a new flutter_markdown_plus_latex that works with our plugin.
