`cargo-asm` panics with `No cdylib?` when called in a `["lib", "cdylib"]` wasm project #292

Hey! I wanted to try using this project to inspect the compiled wasm in this project, however, I get this error when I run cargo asm -p openzeppelin-stylus --wasm -vvv:

Artifact files: ["/Users/alexfertel/work/openzeppelin/rust-contracts-stylus/target/wasm32-unknown-unknown/release/libopenzeppelin_stylus.rlib", "/Users/alexfertel/work/openzeppelin/rust-contracts-stylus/target/wasm32-unknown-unknown/release/openzeppelin_stylus.wasm"]

No cdylib?

I took a look at https://github.com/pacak/cargo-show-asm/issues/203, but it doesn't seem there's much to do on my side.

I also tried compiling the examples of that same project to no avail.

Thanks for the bugreport. Proper fix is blocked upstream https://github.com/rust-lang/cargo/issues/13672, but I made detecting mechanism a bit smarter so it's no longer crashing for me locally on your code.

Thank you very much! It seems to be working well now.
