This adds a "_bin-dependency_" on ``ctru-sys`` to doxygen-rs, a project I've been roking on to improve Doxygen to Rustdoc conversion: https://github.com/Techie-Pi/doxygen-rs
Right now, only basic things are changed (remove ``@`` annotations, trim spaces, etc.).
In the future, changes will be made (mostly to _truly_ transform ``@param``to rustdoc conventions.
Right now, the documentation is mostly decent, and definitely understandable
