Workspace support has broken the example and it's unclear how to proceed

[thoughtpolice]

After #22 was implemented (in f2145de), I'm confused on how to update my Cargo.toml in order to work with reindeer buckify anymore. Absolutely everything I have tried results in the following error:

[ERROR reindeer] parsing metadata
    
    Caused by:
        0: deserializing json
        1: missing field `workspace_default_members` at line 1 column 40613

This exact same error occurs when you attempt to run reindeer buckify on the given examples/ directory Cargo.toml as well. I tried splitting and putting things in workspaces.default-members and several other things; nothing has changed this error at all.

The version of Reindeer is from Nixpkgs; it was built as of commit 7ab6fc8.

Are you using an old cargo? workspace_default_members has been present since 1.71.

[thoughtpolice]

Oh, I was using 1.70, which would explain it then. I can upgrade and try again.

[dtolnay]

Great! Alternatively we'd take a PR to make it work with 1.70 too.

I've tested it, and moving to 1.71 does indeed fix it with no changes to Cargo.toml! Thanks for that.

As for closing this and moving forward, I could try to submit a PR to make it work with previous versions, but I'm rather busy right now and may not have time for it; in the meantime it might also be good to warn in the README at least that you need a recent Cargo.
