ANSI characters & Texture Coloring

Hey @saccharineboi this is a pretty amazing project!!! I'm honestly surprised why its not more popular.

In the future I kind of want to use this library to build some cool things on top, but for now I'd like to ask some questions/request some features.

One pretty cool thing I was wondering if possible was the ability to specify different ANSI character sets. For example, it seems you are rendering full blocks, but since you are using the notcurses backend would it be possible to add more options, such as vhalf blocks, sextant blocks, or the wedge blocks? Maybe even using more of the true image protocols like sixel, kitty, etc. Ideally, I imagine this to just be an option that is sent to notcurses rendering. Of course the speed will be slower, the more symbols that have to be rendered but I'm not particularly concerned about that right now and in any case, those optimizations should be done inside of notcurses itself.

Another thing that would be pretty neat would be showing the colors from the input OBJ files! I think the colors are part of the texture in the OBJ/MTL files, and it seems that you do have textures listed as a known issue. Going through the examples, you already seem to be able to specify color. It'd be pretty nice to have color support if the OBJ file supports it!

The first use case I'd like to start with when using this project would be to create a simple OBJ viewer for arbitrary ANSI resolutions and using the colors from the OBJ file instead of using say lighting via raytracing from light sources.

Thanks so much by the way for creating something like this, its pretty slick!

flto link issues on CentOS Stream 8

Compiling as-is (with GCC) on CentOS Stream 8 fails to link due to some weird error involving flto:

Not sure why this is needed on CentOS and not Ubuntu
