Subject: [PATCH] Upgrade to SNAFU 0.9

Thanks for using SNAFU! I've just released version 0.9 and my tests
caught that your crate would be affected by some of the
SemVer-incompatible changes in this version. See the [CHANGELOG][] for
a full list.

This commit tries to make the minimal amount of changes to get your
code compiling again, but it's entirely possible that there are better
solutions for your specific case.

This version also updates the minimum supported Rust version to Rust
1.65 and targets Rust 1.81 by default. I didn't check how these
changes affect might your crate, so please make sure to use your
judgment as well!

Please feel free to take this PR in whatever form is useful to you;
I'm not interested in becoming a long-term contributor to your
project, so I'd prefer to not learn your project-specific rules or
sign anything like a CLA. I don't mind someone with project approval
yoinking these changes and committing it themselves and side-stepping
all the red tape.
