Cryptic error without a tty

[LegNeato]

When running w/o a tty (for example, in CI), if you use a command where cargo-gpu needs to ask you something, you get a cryptic error. Adding --auto-install-rust-toolchain, which makes cargo-gpu not require a tty, shows no error.

Is the repo and build public?

Yep! Rust-GPU/VulkanShaderExamples#3. Don't mind the messy PR history 🤣
