LEA v3.1.0 — Windows build and auto generation of IV

Full Changelog: v3.0.0...v3.1.0

🚀 Notable Changes

• Windows Build Support

  • Official Windows-compatible build now available, expanding platform support. #30 #31

• Automatic IV Generation

  • The Initialization Vector (IV) is now generated automatically for each encryption operation, improving security and reducing user error. #29
  • Expanded metadata struct: version, mode, and IV fields are now included for better file identification and future compatibility.

• Decryption Output Improvements

  • Improved handling for writing and stripping padding on decryption, ensuring output files exactly match their original sizes.
  • Refactored binary stream writing logic to be more robust and avoid panics when handling the last block of data.

• Error Handling & Reporting

  • Enhanced error reporting and panic handling, especially for out-of-bounds slice accesses during block conversion and file writing.
  • Improved error messages and logging during encryption and decryption operations.

• Documentation & Codebase

  • Added documentation and comments to clarify cryptographic block handling and file I/O.
  • Refactored internal APIs to use []uint32 and [4]uint32 more safely and idiomatically.
  • More robust hooks for progress and UI updates.

🐞 Bug Fixes

• Fixed a runtime panic caused by out-of-range slice access when converting [4]uint32 to []byte.
• Corrected logic for writing only the necessary number of bytes on the last decrypted block, preventing file size mismatches and padding leaks.
