zig-flake: a better Nix flake for building Zig projects

[earnest stream]

After getting frustrated with the existing options, I've created a new Nix flake for Zig. It provides Nix packages for the official binary builds, as well as helpers for creating Nix packages for your own Zig projects.
A comprehensive comparison with the alternatives can be found in the readme, but here's a summary of zig-flake's unique featureset:

• zero dependencies other than nixpkgs
• a dependency fetcher using the zig package manager, that uses your existing build.zig.zon and only requires updating a single hash when dependencies change
• a simple zig.makePackage helper that handles all the packaging for you - just update the depsHash whenever you change your build.zig.zon!
• a setup hook if you want to call stdenv.mkDerivation directly
• drop-in compatibility with zig-overlay (as used by zls, etc)
• frequent update checks - latest zig releases will be available no more than half an hour after they're published on ziglang.org

thanks for making this! already started using it

Why is compat in another branch and not intergrated into main by default?

to avoid cluttering up nix flake show - ideally, most consumers of the flake would use the canonical names, rather than requiring the compat layer

Fun fact: zig.fetchDeps exists

I know ^-^
my version avoids copying the whole source tree to the build dir, which can be expensive for certain projects (eg. games that store assets in the same repo as sources)

Oh, I would accept a PR to fix it lol. I didn't know that just having the zon file works
