rust: bump curve25519-dalek from 3.0.0 to 3.1.0

[dependabot]

Bumps curve25519-dalek from 3.0.0 to 3.1.0.

Changelog

Sourced from curve25519-dalek's changelog.

3.1.0

• Add support for the Elligator2 encoding for Edwards points.
• Add two optional formally-verified field arithmetic backends which use the Fiat Crypto project's Rust code, which is generated from proofs of functional correctness checked by the Coq theorem proving system.
• Add support for additional sizes of precomputed tables for basepoint scalar multiplication.
• Fix an unused import.
• Add support for using the zeroize traits with all point types. Note that points are not automatically zeroized on Drop, but that consumers of curve25519-dalek should call these methods manually when needed.

3.0.2

• Fixes to make using alloc+no_std possible for stable Rust.

3.0.1

• Update the optional packed-simd dependency to rely on a newer, maintained version of the packed-simd-2 crate.
