chore(deps): update constant_time_eq requirement from 0.1.5 to 0.3.0

[dependabot]

Updates the requirements on constant_time_eq to permit the latest version.

Changelog

Sourced from constant_time_eq's changelog.

0.3.0

• Use black_box instead of volatile read when inline assembly is not available.
• Increase minimum Rust version to 1.66, which is when black_box was stabilized.

0.2.6

• New tests using the count_instructions crate; no functional changes.

0.2.5

• Add #[must_use] to all functions.

0.2.4

• Since CC0 is no longer accepted as a license for code by Fedora, also allow MIT-0 or Apache-2.0 as options. No code changes.

0.2.3

• Add fixed-size variant for arrays of any size (using const generics).

0.2.2

• Set rust-version in Cargo.toml to 1.59.

0.2.1

• Reduce inlining of variable-size variant. In 0.1.5, the loop was not inlined, and it can be a bit large due to the auto-vectorization. Go back to how it was in 0.1.5, but allowing the compiler to inline if it believes it would be a speed gain.

0.2.0

• Use inline assembly when available to hide from the optimizer.
• When inline assembly is not available, use both a volatile read and disabled inlining.
• Increase minimum Rust version to 1.59, which is the first with inline assembly.

0.1.5

• Add fixed-size variant for arrays with sizes 16 bytes, 32 bytes, and 64 bytes.
