SDF Font Support

The go-to way to render text at variable sizes with Raylib is to use SDF Font generation, see the following raylib example: https://www.raylib.com/examples/text/loader.html?name=text_font_sdf

There are no c++ bindings to load in a font in this way (for example, no `LoadFontData` bindings passing in a non-default font type / `GenImageFontAtlas` bindings AFAIK). Any chance these could be added?
