Support package renaming inside dev-dependencies

[Fuuzetsu]

It already works for dependencies and build-dependencies, just seems like an oversight.

I ran cargo test, seems to pass.

Fixes #223.

Thanks!

Would you mind adding a test?

[Fuuzetsu]

I'm not sure how. I changed sample_projects/renamed_build_deps/Cargo.toml to include something like

diff --git a/sample_projects/renamed_build_deps/Cargo.toml b/sample_projects/renamed_build_deps/Cargo.toml
index 8c26807..e49ffa7 100644

+# Checks that renames in dev-dependencies work.
+[dev-dependencies]
+futures01 = { package = "futures", version = "0.1", default-features = false }

I ran cargo check to update the lock file and then I ran ./run_tests.sh. It just told me that everything looks OK except uncommitted changes. Cargo.nix doesn't seem updated there. Running ./regenerate_cargo_nix.sh explicitly doesn't seem to help either.

Any suggestion? Or if it's faster for you to add one, feel free...

It took some digging, but the file that confusingly wasn't changing is just dead code! https://github.com/kolloch/crate2nix/pull/245

I am making the tests needed, so don't worry about it :)
