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• Deprecate the sodiumoxide backend, as that crate is no longer maintained.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.
