Implement easy mirroring solution

[mlugg]

Right now, the easiest way to set up a mirror is using Mach's Wrench. This works pretty well, but is written in Go and is part of a larger project. It'd be nice to have a more minimal solution.

So, we should make one! It should expose an HTTP server locally, take requests for files, and cache them in a given directory, with some reasonable eviction policy. SSL is out of scope for this project; a local web server can be used to rproxy to the mirror software instead.

I reckon this should be pretty easily doable in a couple of hundred lines of Zig.

Hi, I would like to give it a try, where do you think we can put this mirror? this repo or something else.

new repo would definitely make the most sense

i'd bet you could even do it in pure caddy or nginx config without any zig at all, but that exploration would be up to whoever decided to tackle this

This is my initial implementation, any feedback is welcome.
