11 adding post quantum support

[Nichokas]

This pull request introduces several changes to the codebase, focusing on adding new dependencies, updating benchmarks, and modifying encryption and key exchange functionalities. The most important changes include the addition of new dependencies, the creation of new benchmark files for kyber and chacha, and significant modifications to the encryption and key exchange implementations.

New Dependencies:

• Added kyberlib, rand, and zerocopy to Cargo.toml to support new cryptographic functionalities.

Benchmark Updates:

• Created new benchmark file benches/chacha_bench.rs to benchmark ChaCha20-Poly1305 key derivation, encryption, and decryption.
• Created new benchmark file benches/kyber_bench.rs to benchmark Kyber keypair generation, encapsulation, decapsulation, and full encryption/decryption.
• Removed old benchmark files benches/encryption.rs and benches/key_exchange.rs which were based on x25519-dalek. [1] [2]

Encryption and Key Exchange Modifications:

• Modified src/encryption.rs to use anyhow for error handling and updated the encryption function to remove unnecessary mut keyword. [1] [2]
• Updated src/key_exchange.rs to replace x25519-dalek with Kyber for key exchange and added new structures for client and server handshakes.
• Updated src/lib.rs to integrate Kyber-based encryption and decryption, replacing the previous x25519-dalek-based implementation.

Documentation:

• Updated the README.md file to reflect changes in the CodSpeed Badge URL.

Main File:

• Added a new src/main.rs file to generate and verify encrypted data using the new Kyber-based encryption scheme.

Performance does not apply its a security fix that obviously its going to use more resources
