Re:Build faster with Buck2: Our open source build system

Just using `cargo build` will work as you've seen, but building a Nix package won't work right now. If you're still keeping up with this thread, though, I have code in this repository to build a copy of buck2 with Nix -- it's several weeks out of date at this point though:
- https://github.com/thoughtpolice/buck2-nix/tree/main/buck/ni...
You should mostly be able to just 'callPackage' that and have it work if you have rust-overlay applied. Check the corresponding 'flake.nix' if you need it.
The prost issue with buildRustPackage is preventing an upgrade, so ideally the minor patches to prost can get upstreamed, but I need to (again) file a ticket about moving this along.
crane.dev with nightly-2023-03-15 from oxalica/rust-overlay built here okay (after I figured out all the BUCK2_BUILD_PROTOC, missing Cargo.lock, etc tricks).
I did have some weird trouble with trying to import buck2 into my flake as a non-flake input, with complaints about "failed to resolve patches" for prost, but putting the flake.nix into the buck2 source tree worked.
