feat: Implement C# EXI encoder based on C iso1EXIDatatypesEncoder

- Complete EXI encoder implementation for CurrentDemandReq messages
- Uses exact C grammar states and bit patterns
- 7-bit choice (76) for V2G_Message document encoding
- 6-bit choice (13) for CurrentDemandReq body encoding
- Proper grammar state machine following C version
- Fixed bit patterns and integer encoding methods
- All compilation errors resolved

Progress: Basic encoding functionality working, produces 49 bytes vs target 43 bytes
Next: Fine-tune to match exact C version byte output
