chore(deps): update snafu requirement from 0.6.10 to 0.7.0

[dependabot[bot]]

Updates the requirements on snafu to permit the latest version.

Changelog

Sourced from snafu's changelog.

[0.7.0] - XXXX-XX-XX

Added

• A crate prelude containing common macros and traits can be imported via use snafu::prelude::*.

• A ready-to-use error type Whatever is available to quickly start reporting errors with little hassle.

• "Stringly typed" error cases can be added to existing error types, allowing you to construct errors without defining them first.

• Formatting shorthand syntax for error type data fields is now supported: #[snafu(display("Hello {name}"))].

• [snafu(module)] can be specified on an error type. This will create a module for the error type and all associated context selectors will be placed in that module.

• snafu::Location can be added to an error type to provide lightweight tracking of the source location where the error was created.

• [snafu(implicit)] can be specified on context selector data fields to automatically generate it via snafu::GenerateImplicitData when the error is created.

• ErrorCompat::iter_chain provides an iterator over the list of causal errors.

Changed

• Generated context selectors now have the suffix Snafu. This is a breaking change.

• ResultExt::with_context, TryFutureExt::with_context, and TryStreamExt::with_context now pass the error into the closure. This is a breaking change.

• The GenerateBacktrace trait has been split into GenerateImplicitData and AsBacktrace. This is a breaking change.

• Rust 1.34 is now the minimum supported Rust version. This is a breaking change.

Removed

• String attribute parsing (#[snafu(foo = "...")]) is no longer

wait, why do we even depend on this?

[dependabot[bot]]

A newer version of snafu exists, but since this PR has been edited by someone other than Dependabot I haven't updated it. You'll get a PR for the updated version as normal once this PR is merged.

Seems to be for https://github.com/tokio-rs/tracing/blob/c4bcf5c2c48cc82b7fe11a657a9733c7d73c4ed9/examples/examples/fmt/yak_shave.rs#L63-L67

tracing-examples might need some manual changes in order to be able to do this version bump, CI fails with
