FRANZEN Enhancements

Added

• Experimental FRANZEN function now stores CRC-32 of encrypted file blocks in the header.
• New work crc32 command for quick integrity checks without requiring the encryption password.

Improved

• CRC-32 computation uses multi-threaded block processing, similar to zpaqfranz.
• Verification function skips the first 140 bytes (128 + 12) and processes the rest efficiently.
• Supports high-speed integrity checks for cloud transmission on standard machines.

Notes

• CRC-32 is not cryptographic; it only provides a fast integrity check.
• Full verification still requires work test with the encryption password.
• Additional checks are planned for future refinements.
