build(deps): bump bytemuck_derive from 1.8.1 to 1.9.1

[dependabot]

Bumps bytemuck_derive from 1.8.1 to 1.9.1.

Changelog

Sourced from bytemuck_derive's changelog.

1.9.1

• Bumped the minimum bytemuck_derive dependency version from 1.0 to 1.1. The fact that bytemuck and bytemuck_derive are separate crates at all is an unfortunate technical limit of current Rust, woe and calamity.

1.9.0

• fu5ha added the NoUninit, AnyBitPattern, and CheckedBitPattern traits. This allows for a more fine-grained level of detail in what casting operations are allowed for a type. Types that already implement Zeroable and Pod will have a blanket impl for these new traits. This is a "preview" of the direction that the crate will probably go in the eventual 2.0 version. We're still waiting on Project Safe Transmute for an actual 2.0 version of the crate, but until then please enjoy this preview.
• Also Fusha added better support for union types in the derive macros. I still don't know how any of the proc-macro stuff works at all, so please direct questions to her.

1.8.0

• try_pod_read_unaligned and pod_read_unaligned let you go from &[u8] to T:Pod without worrying about alignment.

1.7.3

• Experimental support for the portable_simd language extension under the nightly_portable_simd cargo feature. As the name implies, this is an experimental crate feature and it's not part of the semver contract. All it does is add the appropriate Zeroable and Pod impls.

1.7.2

• Why does this repo keep being hit with publishing problems? What did I do to deserve this curse, Ferris? This doesn't ever happen with tinyvec or fermium, only bytemuck.

1.7.1

• Soundness Fix: The wrap/peel methods for owned value conversion, added to TransparentWrapper in 1.6, can cause a double-drop if used with types that impl Drop. The fix was simply to add a ManuallyDrop layer around the value before doing the transmute_copy that is used to wrap/peel. While this fix could technically be backported to the 1.6 series, since 1.7 is semver compatible anyway the 1.6 series has simply been yanked.

1.7

• In response to [Unsafe Code Guidelines Issue
