Bump snow from 0.9.2 to 0.9.6

[dependabot]

Bumps snow from 0.9.2 to 0.9.6.

Release notes

Sourced from snow's releases.

v0.9.6

• Validate invalid PSK positions when building a Noise protocol.
• Raise errors in various typos/mistakes in Noise patterns when parsing.
• Deprecate the sodiumoxide backend, as that crate is no longer maintained. We may eventually migrate it to a maintaned version of the crate, but for now it's best to warn users.
• Set a hard limit in read_message() in transport mode to 65535 to be fully compliant with the Noise specification.

Full Changelog: mcginty/snow@v0.9.5...v0.9.6

v0.9.5

This is a security release that fixes a logic flaw in decryption in TransportState (i.e. the stateful one), where the nonce could increase even when decryption failed, which can cause a desync between the sender and receiver, opening this up as a denial of service vector if the attacker has the ability to inject packets in the channel Noise is talking over.

More details can be found in the advisory: GHSA-7g9j-g5jg-3vv3

All users are encouraged to update.

v0.9.4

This is a dependency version bump release because a couple of important dependencies released new versions that needed a Cargo.toml bump:

• ring 0.17
• pqcrypto-kyber 0.8
• aes-gcm 0.10
• chacha20poly1305 0.10

v0.9.3

This is a quick patch release to use the stable 4.0 version of curve25519-dalek.
