chacha20poly1305 0.6.0

Pure Rust implementation of the ChaCha20Poly1305 Authenticated Encryption with Additional Data Cipher (RFC 8439) with optional architecture-specific hardware acceleration. Also contains implementations of the XChaCha20Poly1305 extended nonce variant of ChaCha20Poly1305, and the reduced-round ChaCha8Poly1305 and ChaCha12Poly1305 lightweight variants.
