Subject: [PATCH] Add V2G library project and refactor code structure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Create V2GProtocol.Library project for DLL usage by external programs
- Add V2GApi.cs with public API methods for EXI encoding/decoding
- Move helper functions to Helper.cs for better code organization
- Update project configuration for .NET Framework 4.8
- Translate all comments in Program.cs to Korean
- Fix .hex file handling to read as binary instead of text
