WASI Support

[ainaracatgirl]

Hi! I'm working on a Web Assembly Systems Interface (WASI) Operating System for the browser and would like to know if it is possible to add support to afetch. I chose afetch because, of all the fetch programs I found, it is the simplest.

There are currently no special files that identify the system (though I will probably add /etc/os-release) but it can be identified through uname.

/ # uname -a
wasi (none) 0.0.0 0.0.0 wasm32
/ # uname -s
wasi

It would be really cool to see nice ASCII art for WebAssembly in afetch!
