Cyclic dev-dep needs help when publishing

[jayvdb]

We're in the process of publishing a new butane to https://cloudsmith.io, and ran into rust-lang/cargo#4242 , because butane_test_helper is a dev-dep of butane_core.

I am not a fan of the version range trick suggested at rust-lang/cargo#4242 (comment)

So we're going with the "remove dev-deps and publish dirty" approach like rust-lang/cargo#4242 (comment) . https://github.com/rust-lang/futures-rs/tree/master/ci/remove-dev-dependencies is missing now, but it looks like it should be in the git history. Unfortunately not in crates.io

I was able to publish with

cargo hack publish --allow-dirty -p butane_core --no-dev-deps
cargo hack publish --allow-dirty -p butane_codegen
cargo hack publish --allow-dirty -p butane_test_helper
cargo hack publish --allow-dirty -p butane --no-verify
cargo hack publish --allow-dirty -p butane_cli

Tried making it a one-liner but ran into taiki-e/cargo-hack#188

I think #84 fixes this. Let me know if you see issues with the approach there.

Closing due to the above. Let me know if I missed anything.
