feat: Output Unit and EVErrorCode as numeric values instead of strings

Browse Source 
- Remove get_unit_string() and get_error_string() helper functions
- Output Unit values as numbers (3=A, 4=V, 5=W, 2=s) instead of letters
- Output EVErrorCode as numbers (0) instead of strings (NO_ERROR)
- Maintain compatibility with Wireshark XML format structure
- Add build.bat for easy compilation
- Improve SessionID parsing for namespaced XML tags

This ensures decoded EXI outputs preserve original numeric values
rather than converting them to human-readable strings.
