Unable to use `strip` profile in cargo

[Dengjianping]

Hi, Is there any plan to upgrade rust to 1.59?

I was trying to use strip profile in a project, but srtool gave a error like this:

║ 🧰 Substrate Runtime Toolbox - srtool v0.9.19 🧰

  ║ The package requires the Cargo feature called `strip`, but that feature is not stabilized in this version of Cargo (1.57.0 (b2e52d7ca 2021-10-21)).
  ║ Consider adding `cargo-features = ["strip"]` to the top of Cargo.toml (above the [package] table) to tell Cargo you are opting in to use this unstable feature.

strip has been stabilized in rust .159.

Hello @Dengjianping,

I am now closing this issue as it should be fixed by the new release 0.9.19. That would be great if you could confirm with a short note here.

If you still run into issues however, feel free to re-open.
