Pull Request Overview

This PR implements four new utility packages (YaBase64, YaRSA, YaGzip, YaMiddleware) to provide cryptographic and data encoding functionality with a focus on RSA encryption workflows. The implementation includes deterministic RSA key generation, base64 encoding/decoding, gzip compression, and Gin middleware for encrypted request headers.

Key changes:

• Added RSA encryption/decryption with chunking support for arbitrary data lengths
• Implemented deterministic RSA key generation using HMAC-SHA256 based DRBG
• Created base64 and gzip utility packages with error handling
• Built Gin middleware for processing RSA-encrypted headers with compression
