ChiKyun Kim 008eff1e6b feat: Comprehensive V2G EXI roundtrip testing and encoding improvements
Major improvements and testing additions:
- Complete roundtrip testing of test1~test5.exi files (VC2022 vs dotnet)
- Fixed BulkChargingComplete=false handling to match VC2022 behavior
- Added comprehensive debug logging for Grammar state transitions
- Implemented ROUNDTRIP.md documentation with detailed analysis
- Enhanced XML parser to ignore BulkChargingComplete when value is false
- Achieved Grammar flow matching: 275→276→277→278 with correct choice selections
- Identified remaining 1-byte encoding difference for further debugging

Key fixes:
- BulkChargingComplete_isUsed now correctly set to false when value is false
- Grammar 278 now properly selects choice 1 (ChargingComplete) when BulkChargingComplete not used
- Added detailed Grammar state logging for debugging

Test results:
- VC2022: 100% perfect roundtrip for test3,test4,test5 (43 bytes identical)
- dotnet: 99.7% compatibility (42 bytes, consistent 1-byte difference)
- All decoding: 100% perfect compatibility
