Hi, This commit https://github.com/tokio-rs/prost/commit/30b22d38f0d29bed2bca6a1cac1a9051fdd2443f introduces a breakage because the `pub` functions `protoc_from_env` and `protoc_include_from_env` are moved in the `config.rs` file. Because `config.rs` is privately imported, its `pub` functions are not available anymore from outside crates.
